Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header.

LibHTML: Start working on a simple HTML library. I'd like to have rich text, and we might as well use HTML for that. :^)

#pragma once
LibHTML: Add function for invalidating the document layout This allows any external actor to signal that the document layout may be stale. This can be used when loading resources, changing the size or placement of an element, adding/removing nodes, or really any time.
2019-10-06 14:58:18 +03:00
#include <AK/Function.h>
LibWeb: Give each Node a unique ID We maintain a directory of ID -> Node. Nodes add themselves to this directory when they are created, receiving a random ID. When a Node is destroyed, it removes itself from this directory. Anyone can request a Node from the directory by its ID using `Node::from_id()`. We reserve the `0` ID to mean "none". These IDs allow different processes to communicate about a given Node over IPC, for example the DOM Inspector.
2021-08-30 17:52:08 +03:00
#include <AK/HashMap.h>
LibHTML: Refactor to go from DOM -> styled tree -> layout tree. Frame::layout() drives everything now, it takes the DOM contained in the frame and puts it through the tree transformations.

LibHTML: Add load(URL) and reload() functions to HtmlView You can now pass a file:/// URL to HtmlView and it will take care of the loading logic for you. Each Document remembers the URL it was loaded from, which allows us to also have reload(). This patch also adds a very simple function for resolving relative URL's into absolute ones.
2019-10-05 11:16:27 +03:00
#include <AK/URL.h>
LibWeb: Add stubs for document.write and document.writeln ACID3 test page throws exception about document.write. Let's at least get rid of it by defining these stubs. I added document.writeln too because it is similar.
2022-02-15 19:36:27 +03:00
#include <AK/Vector.h>
LibHTML: Add a Frame class and use it for document layout width Each HtmlView now has a main_frame(), which represents the main frame of the web page. Frame inherits from TreeNode<Frame>, which will allow us to someday implement a Frame tree (to support the <frame> element.)

LibWeb: Parse <script> elements and run any JavaScript found inside This patch begins integrating LibJS into LibWeb. Document holds the JS::Interpreter for now, and it is created on demand when you first call Document::interpreter(). We also add a simple "alert()" function to the global object.
2020-03-14 14:41:51 +03:00

LibWeb: Split CSS::StyleSheet into StyleSheet and CSSStyleSheet This is a little convoluted but matches the CSSOM specification.
2021-03-07 18:14:04 +03:00
#include <LibWeb/CSS/CSSStyleSheet.h>
LibWeb: Process style sheets in document order Until now we would simply apply stylesheets in the order they finished loading. This patch adds a StyleSheetList object that hangs off of each Document and contains all the style sheets in document order. There's still a lot of work to do for a proper cascade, but at least this makes us consistently wrong every time. :^)

Browser+LibWeb+WebContent: Track the source of document.cookie requests To implement the HttpOnly attribute, the CookieJar needs to know where a request originated from. Namely, it needs to distinguish between HTTP / non-HTTP (i.e. JavaScript) requests. When the HttpOnly attribute is set, requests from JavaScript are to be blocked.

#include <LibWeb/DOM/ParentNode.h>
LibWeb: Remove unecessary dependence on Window from DOM and WebIDL These classes only needed Window to get at its realm. Pass a realm directly to construct DOM and WebIDL classes. This change importantly removes the guarantee that a Document will always have a non-null Window object. Only Documents created by a BrowsingContext will have a non-null Window object. Documents created by for example, DocumentFragment, will not have a Window (soon). This incremental commit leaves some workarounds in place to keep other parts of the code building.
2022-09-26 01:15:49 +03:00
#include <LibWeb/HTML/BrowsingContext.h>
LibWeb: Bring browsing context creation closer to spec This patch implements the "create a new browsing context" function from the HTML spec and replaces our existing logic with it. The big difference is that browsing contexts now initially navigate to "about:blank" instead of starting out in a strange "empty" state. This makes it possible for websites to create a new iframe and start scripting inside it right away, without having to load an URL into it.

LibWeb: Flesh out prepare_script and execute_script This fills in a bunch of the FIXMEs that was in prepare_script. execute_script is almost finished, it's just missing the module side. As an aside, let's not assert when inserting a script element with innerHTML.
2021-01-28 23:31:20 +03:00
#include <LibWeb/HTML/HTMLScriptElement.h>
LibWeb: Add the History object and stub pushState and replaceState The spec allows us to optionally return from these for any reason. Our reason is that we don't have all the infrastructure in place yet to implement them.
2021-09-12 01:43:34 +03:00
#include <LibWeb/HTML/History.h>
LibWeb: Extract shared lazy-loading behavior into a base class `<iframe>` and `<img>` tags share the same spec for several aspects of lazy-loading: how the `loading` attribute works, the "will lazy load element" steps, and a member for storing the lazy-load resumption steps. So let's share the implementation by using a base class. This mostly involves moving things around. However, we also change the `start_intersection_observing_a_lazy_loading_element()` method to take a LazyLoadingElement, and operate on one, instead of always casting to HTMLImageElement. We do unfortunately have to do some shenanigans to make the cast work, by adding a virtual function stub in DOM::Element.

LibWeb: Introduce the Environment Settings Object The environment settings object is effectively the context a piece of script is running under, for example, it contains the origin, responsible document, realm, global object and event loop for the current context. This effectively replaces ScriptExecutionContext, but it cannot be removed in this commit as EventTarget still depends on it. https://html.spec.whatwg.org/multipage/webappapis.html#environment-settings-object

#include <LibWeb/HTML/Scripting/Environments.h>
LibWeb: Forbid sharing image requests across documents This change addresses the bug where images unable to load when the reload button in the UI is clicked repeatedly. Before this fix, it was possible to use SharedImageRequests across multiple documents. However, when the document that initiated the request is gone, tasks scheduled on the event loop remain in the fetching state because the originating document is no longer active. Furthermore, another reason to prohibit the sharing of image requests across documents is that the "Origin" header in an image request is dependent on the document.

LibWeb+WebContent+Browser: Plumb visibility state from GUI to web pages OOPWV now reacts to show/hide events and informs LibWeb about the state change. This makes visibilitychange events fire when switching tabs. :^)

LibWeb+LibWebView+WebContent: Add APIs to manage an autoplay allowlist The spec defines a Permissions Policy to control some browser behaviors on a per-origin basis. Management of these permissions live in their own spec: https://w3c.github.io/webappsec-permissions-policy/ This implements a somewhat ad-hoc Permissions Policy for autoplaying media elements. We will need to implement the entire policy spec for this to be more general.

LibWeb: Add Bindings::ScriptExecutionContext This will be inherited by documents and workers, to provide a common abstraction for script execution. (We don't have workers yet, but we might as well make this little space for them now to simplify things down the road.)

LibWeb: Rewrite EventTarget to more closely match the spec This isn't perfect (especially the global object situation in activate_event_handler), but I believe it's in a much more complete state now :^) This fixes the issue of crashing in prepare_for_ordinary_call with the `i < m_size` crash, as it now uses the IDL callback functions which requires the Environment Settings Object. The environment settings object for the callback is fetched at the time the callback is created, for example, WrapperGenerator gets the incumbent settings object for the callback at the time of wrapping. This allows us to remove passing in ScriptExecutionContext into EventTarget's constructor. With this, we can now drop ScriptExecutionContext.

LibWeb+LibJS: Make the EventTarget hierarchy (incl. DOM) GC-allocated This is a monster patch that turns all EventTargets into GC-allocated PlatformObjects. Their C++ wrapper classes are removed, and the LibJS garbage collector is now responsible for their lifetimes. There's a fair amount of hacks and band-aids in this patch, and we'll have a lot of cleanup to do after this.
2022-08-28 14:42:07 +03:00
WEB_PLATFORM_OBJECT(Document, ParentNode);
LibWeb: Put most LibWeb GC objects in type-specific heap blocks With this change, we now have ~1200 CellAllocators across both LibJS and LibWeb in a normal WebContent instance. This gives us a minimum heap size of 4.7 MiB in the scenario where we only have one cell allocated per type. Of course, in practice there will be many more of each type, so the effective overhead is quite a bit smaller than that in practice. I left a few types unconverted to this mechanism because I got tired of doing this. :^)
2023-11-19 21:47:52 +03:00
JS_DECLARE_ALLOCATOR(Document);
LibWeb: Start implementing basic JavaScript DOM bindings This patch introduces the Wrapper and Wrappable classes. Node now inherits from Wrappable, and can be wrapped in a GC-allocated Bindings::NodeWrapper object. The only property we expose right now is the very simple nodeName property. When a Document's JS::Interpreter is first instantiated, we add a "document" property with a DocumentWrapper object to the global object. This is pretty cool! :^)

LibWeb: Start implementing "create and initialize a Document" from HTML The way we've been creating DOM::Document has been pretty far from what the spec tells us to do, and this is a first big step towards getting us closer to spec. The new Document::create_and_initialize() is called by FrameLoader after loading a "text/html" resource. We create the JS Realm and the Window object when creating the Document (previously, we'd do it on first access to Document::interpreter().) The realm execution context is owned by the Environment Settings Object.

This has the unfortunate side-effect of requiring us to use the fully qualified AK::URL name whenever we want to refer to the AK class, so this commit also fixes all such references.

The modern sign in page has this near the beginning: ```html <base href="https://accounts.google.com"> ``` All of the XHRs performed by sign in are relative URLs to this base URL. Previously we ignored this and did it relative to the current URL, causing the XHRs to 404 and sign in to fall apart. I presume they do this because you can access the sign in page from multiple endpoints, such as `/ServiceLogin` and `/o/oauth2/auth/identifier`

LibWeb: Cache the first <base href> (in tree order) in Document When parsing relative URLs, we have to check the first <base href> in tree order (if one is available). This was getting *very* costly on large DOMs with many relative urls. This patch avoids all that repeated traversal by letting Document cache the first <base href> and invalidating the cache whenever a <base> element is added/removed/edited in the DOM. The browser was stuck doing this for a *very* long time when loading the ECMA-262 spec, and this removes that problem entirely.

LibWeb: Rename CSS::StyleResolver => StyleComputer Resolved style is a spec concept that refers to the weird mix of computed style and used style reflected by getComputedStyle(). The purpose of this class is to produce the *computed* style for a given element, so let's call it StyleComputer.

LibWeb+LibJS: Make the EventTarget hierarchy (incl. DOM) GC-allocated This is a monster patch that turns all EventTargets into GC-allocated PlatformObjects.

LibWeb: Start exposing CSS style sheets to JavaScript :^) This patch adds bindings for the following objects: - StyleSheet - StyleSheetList - CSSStyleSheet You can get to a document's style sheets via Document.styleSheets and iterate through them using StyleSheetList's item() and length(). That's it in terms of functionality at this point, but still neat. :^)

2023-09-17 01:51:43 +03:00

LibHTML: Add virtual Node::tag_name() This is analogous to the DOM's Node.tagName and makes it easy to ask "hey, what kinda thing is this Node?"
2019-09-28 23:59:16 +03:00
LibHTML: Implement basic :hover pseudo-class support This is currently very aggressive. Whenever the Document's hovered node changes, we invalidate all style and do a full relayout. It does look cool though. So cool that I'm adding it to the default stylesheet. :^)

LibWeb: Wrap PseudoElements stored in SimpleSelector in a class No functional impact intended. This is just a more complicated way of writing what we have now. The goal of this commit is so that we are able to store the 'name' of a pseudo element for use in serializing 'unknown -webkit- pseudo-elements', see: https://www.w3.org/TR/selectors-4/#compat This is quite awkward, as in pretty much all cases just the selector type enum is enough, but we will need to cache the name for serializing these unknown selectors. I can't figure out any reason why we would need this name anywhere else in the engine, so pretty much everywhere is still just passing around this raw enum. But this change will allow us to easily store the name inside of this new struct for when it is needed for serialization, once those webkit unknown elements are supported by our engine.

HTML::BrowsingContext* browsing_context() { return m_browsing_context.ptr(); }
HTML::BrowsingContext const* browsing_context() const { return m_browsing_context.ptr(); }
LibHTML: Add a Frame class and use it for document layout width Each HtmlView now has a main_frame(), which represents the main frame of the web page. Frame inherits from TreeNode<Frame>, which will allow us to someday implement a Frame tree (to support the <frame> element.)
2019-10-04 16:50:04 +03:00
LibWeb: Implement Document/BrowsingContext hookup according to spec We now implement the browsing context's "set active document" algorithm from the spec, as well as the "discard" algorithm for browsing contexts and documents.

LibWeb: Make Document::page() return a Page& Now that Document always has a Page, and always keeps it alive, we can make this return a Page&, exposing various unnecessary null checks.
2023-12-15 17:41:28 +03:00
Page& page();
Page const& page() const;
LibWeb: Make Frame point weakly to Page This patch makes Page weakable and allows page-less frames to exist. Page is single-owner, and Frame is multiple-owner, so it's not sound for Frame to assume its containing Page will stick around for its own entire lifetime. Fixes #3976.

Color background_color() const;
LibWeb: Store background layers in ComputedValues Instead of storing these as individual `background-foo` properties, we combine them together into layers, since that is how they will be painted. It also makes it more convenient to pass them around.
2021-11-12 15:11:01 +03:00
Vector<CSS::BackgroundLayerData> const* background_layers() const;
LibHTML: Add support for <body bgcolor="#rrggbb" text="#rrggbb"> This patch implements basic support for presentational hints, which are old-school HTML attributes that affect style. You add support for a presentational hint attribute by overriding Element::apply_presentational_hints(StyleProperties&) and setting all of the corresponding CSS properties as appropriate. To make the background color fill the entire document, not just the bounds of the <body> element's LayoutNode, we special-case it in the HtmlView::paint_event() code for now. I'm not entirely sure what the nicest solution would be, but I'm sure we'll discover it eventually.
2019-10-04 22:05:52 +03:00
LibDraw+LibHTML: Make link colors themeable Add "Link", "ActiveLink" and "VisitedLink" colors to the system theme definition, and implement support for them in LibHTML. Note that <body link="foo" alink="bar" vlink="baz"> takes precedence over the system colors. Author style also takes precedence, since we only fetch the system color in case the CSS color is -libhtml-link.

2019-10-28 22:51:45 +03:00
void force_layout();
LibHTML: Move layout root from HtmlView to Document The layout root is now kept alive via Document::m_layout_root. This will allow us to do more layout-related things inside the inner layer of LibHTML without reaching out to the HtmlView. I'd like to keep HtmlView at a slightly higher level, to prevent it from getting too complex. This patch also fixes accidental disconnection of the layout tree from the DOM after doing a layout tree rebuild. ~LayoutNode() now only unsets the DOM node's layout_node() if it's itself.
2019-10-13 13:34:25 +03:00
LibHTML: Rename Document's invalidate_{style,layout}() to update_foo()
2019-10-14 18:56:19 +03:00
void update_style();
void update_layout();
LibHTML: Add function for invalidating the document layout This allows any external actor to signal that the document layout may be stale. This can be used when loading resources, changing the size or placement of an element, adding/removing nodes, or really any time.
2019-10-06 14:58:18 +03:00
LibWeb: Make CSS layout lazier Instead of doing layout synchronously whenever something changes, we now use a basic event loop timer to defer and coalesce relayouts. If you did something that requires a relayout of the page, make sure to call Document::set_needs_layout() and it will get coalesced with all the other layout updates. There's lots of room for improvement here, but this already makes many web pages significantly snappier. :^) Also, note that this exposes a number of layout bugs where we have been relying on multiple relayouts to calculate the correct dimensions for things. Now that we only do a single layout in many cases, these kind of problems are much more noticeable. That should also make them easier to figure out and fix. :^)
2021-10-05 23:30:53 +03:00
void set_needs_layout();
LibWeb: Always relayout document on element style change Let's get this right before trying to make it fast. This patch removes the code that tried to do less work when an element's style changes, and instead simply invalidates the entire document. Note that invalidations are still coalesced, and will not be synchronized until update_style() and/or update_layout() is used.
2022-03-09 19:57:45 +03:00
void invalidate_layout();
LibWeb: Only invalidate stacking context tree for opacity/z-index change I came across some websites that change an elements CSS "opacity" in their :hover selectors. That caused us to relayout on hover, which we'd like to avoid. With this patch, we now check if a property only affects the stacking context tree, and if nothing layout-affecting has changed, we only invalidate the stacking context tree, causing it to be rebuilt on next paint or hit test. This makes :hover { opacity: ... } rules much faster. :^)

virtual bool is_child_allowed(Node const&) const override;
LibHTML: Add Comment and CharacterData nodes and improve HTML parsing This patch adds the CharacterData subclass of Node, which is now the parent class of Text and a new Comment class. A Comment node is one of these in HTML: <!--hello friends--> Since these occur somewhat frequently on the web, we need to be able to parse them. This patch also adds a child rejection mechanism to the DOM tree. Nodes can now override is_child_allowed(Node) and return false if they don't want a particular Node to become a child of theirs. This is used to prevent Document from taking on unwanted children.
2019-10-13 00:26:47 +03:00

LibHTML: Batch style updates and make them start from the root Use a zero-timer to schedule a style update after invalidating style on any node. Nodes now have a needs_style_update flag which helps us batch and coalesce the work. We also start style updates at the root and work our way through the document, updating any node that has the needs_style_update flag set. This is slower than what we were doing before, but far more correct. There is a ton of room for improvement here. :^)

LibWeb: Bring browsing context creation closer to spec This patch implements the "create a new browsing context" function from the HTML spec and replaces our existing logic with it. The big difference is that browsing contexts now initially navigate to "about:blank" instead of starting out in a strange "empty" state. This makes it possible for websites to create a new iframe and start scripting inside it right away, without having to load an URL into it.

WebIDL::ExceptionOr<void> write(Vector<String> const& strings);

LibWeb: Add basic support for dynamic markup insertion This implements basic support for dynamic markup insertion, adding * Document::open() * Document::write(Vector<String> const&) * Document::writeln(Vector<String> const&) * Document::close() The HTMLParser is modified to make it possible to create a script-created parser which initially only contains a HTMLTokenizer without any data. Aditionally the HTMLParser::run method gains an overload which does not modify the Document and does not run HTMLParser::the_end() so that we can reenter the parser at a later time. Furthermore all FIXMEs that consern the insertion point are implemented wich is defined in the HTMLTokenizer. Additionally the following member-variables of the HTMLParser are now exposed by getter funcions: * m_tokenizer * m_aborted * m_script_nesting_level The HTMLTokenizer is modified so that it contains an insertion point which keeps track of where the next input from the Document::write functions will be inserted. The insertion point is implemented as the charakter offset into m_decoded_input and a boolean describing if the insertion point is defined. Functions to update, check and {re}store the insertion point are also added. The function HTMLTokenizer::insert_eof is added to tell a script-created parser that document::close was called and HTMLParser::the_end() should be called. Lastly an explicit default constructor is added to HTMLTokenizer to create a empty HTMLTokenizer into which data can be inserted.

It also implements the has_encoding() and encoding_or_default() instance methods, the latter of which will return "UTF-8" as a fallback if no encoding is present. The usage of Optional<String> instead of the null string is part of an effort to explicitly indicate that a string could not have a value. This also modifies the former callers of encoding() to use encoding_or_default(). Furthermore, the encoding will now only be set if it is actually known, rather than just guessed by earlier code.

LibWeb: Move viewport subscriptions from BrowsingContext to Document With this change, elements that want to receive viewport rect updates will need to register on document instead of the browsing context. This change solves the problem where a browsing context for a document is guaranteed to exist only while the document is active so browsing context might not exit by the time DOM node that want to register is constructed. This is a part of preparation work before switching to navigables where this issue becomes more visible.

LibWeb: Make document.write() work while document is parsing This necessitated making HTMLParser ref-counted, and having it register itself with Document when created. That makes it possible for scripts to add new input at the current parser insertion point. There is now a reference cycle between Document and HTMLParser. This cycle is explicitly broken by calling Document::detach_parser() at the end of HTMLParser::run(). This is a huge progression on ACID3, from 31% to 49%! :^)

LibWeb: Don't parse inline style sheets during HTML fragment parsing Some websites (like Reddit) like to instantiate "components" by setting innerHTML to a huge chunk of stuff. Sometimes those huge chunks of stuff contain inline style sheets (i.e `<style>` elements). Before this change, we would end up parsing the CSS in those elements multiple times, because we had no way of knowing that we were within a fragment parser's temporary document. This patch avoids the extra CSS parsing work by adding adding a flag to Document that tells us it's being used by the fragment parser. Then, we simply avoid parsing CSS for style elements in such documents. The CSS then gets parsed immediately upon insertion into the proper DOM.

However, we also change the `start_intersection_observing_a_lazy_loading_element()` method to take a LazyLoadingElement, and operate on one, instead of always casting to HTMLImageElement.

LibWeb: Forbid sharing image requests across documents This change addresses the bug where images unable to load when the reload button in the UI is clicked repeatedly. Before this fix, it was possible to use SharedImageRequests across multiple documents. However, when the document that initiated the request is gone, tasks scheduled on the event loop remain in the fetching state because the originating document is no longer active. Furthermore, another reason to prohibit the sharing of image requests across documents is that the "Origin" header in an image request is dependent on the document.

LibWeb: Basic implementation of global event handlers :^) Document and HTMLElement now inherit from HTML::GlobalEventHandlers which allows them to support "onfoo" event handler attributes. These are assignable both via IDL attributes and content attributes. Event listeners constructed this way get a special "attribute" flag on them so we know which one to replace if you reassign them. This also allows them to coexist with EventTarget.addEventListener(). This is all a bit sloppy, but it works decently for a first cut. The Window object should also inherit GlobalEventHandlers, but since we don't generate it from IDL, I haven't taken that step here. Also this would be a lot nicer if we supported IDL mixins.

LibWeb: Wrap PseudoElements stored in SimpleSelector in a class No functional impact intended. This is just a more complicated way of writing what we have now. The goal of this commit is so that we are able to store the 'name' of a pseudo element for use in serializing 'unknown -webkit- pseudo-elements', see: https://www.w3.org/TR/selectors-4/#compat This is quite awkward, as in pretty much all cases just the selector type enum is enough, but we will need to cache the name for serializing these unknown selectors. I can't figure out any reason why we would need this name anywhere else in the engine, so pretty much everywhere is still just passing around this raw enum. But this change will allow us to easily store the name inside of this new struct for when it is needed for serialization, once those webkit unknown elements are supported by our engine.

This is slower than what we were doing before, but far more correct. There is a ton of room for improvement here. :^)

LibWeb: Add basic support for dynamic markup insertion This implements basic support for dynamic markup insertion, adding * Document::open() * Document::write(Vector<String> const&) * Document::writeln(Vector<String> const&) * Document::close() The HTMLParser is modified to make it possible to create a script-created parser which initially only contains a HTMLTokenizer without any data. Aditionally the HTMLParser::run method gains an overload which does not modify the Document and does not run HTMLParser::the_end() so that we can reenter the parser at a later time. Furthermore all FIXMEs that consern the insertion point are implemented wich is defined in the HTMLTokenizer. Additionally the following member-variables of the HTMLParser are now exposed by getter funcions: * m_tokenizer * m_aborted * m_script_nesting_level The HTMLTokenizer is modified so that it contains an insertion point which keeps track of where the next input from the Document::write functions will be inserted. The insertion point is implemented as the charakter offset into m_decoded_input and a boolean describing if the insertion point is defined. Functions to update, check and {re}store the insertion point are also added. The function HTMLTokenizer::insert_eof is added to tell a script-created parser that document::close was called and HTMLParser::the_end() should be called. Lastly an explicit default constructor is added to HTMLTokenizer to create a empty HTMLTokenizer into which data can be inserted.

LibWeb: Add basic support for dynamic markup insertion This implements basic support for dynamic markup insertion, adding * Document::open() * Document::write(Vector<String> const&) * Document::writeln(Vector<String> const&) * Document::close() The HTMLParser is modified to make it possible to create a script-created parser which initially only contains a HTMLTokenizer without any data. Aditionally the HTMLParser::run method gains an overload which does not modify the Document and does not run HTMLParser::the_end() so that we can reenter the parser at a later time. Furthermore all FIXMEs that consern the insertion point are implemented wich is defined in the HTMLTokenizer. Additionally the following member-variables of the HTMLParser are now exposed by getter funcions: * m_tokenizer * m_aborted * m_script_nesting_level The HTMLTokenizer is modified so that it contains an insertion point which keeps track of where the next input from the Document::write functions will be inserted. The insertion point is implemented as the charakter offset into m_decoded_input and a boolean describing if the insertion point is defined. Functions to update, check and {re}store the insertion point are also added. The function HTMLTokenizer::insert_eof is added to tell a script-created parser that document::close was called and HTMLParser::the_end() should be called. Lastly an explicit default constructor is added to HTMLTokenizer to create a empty HTMLTokenizer into which data can be inserted.

LibWeb: Move viewport subscriptions from BrowsingContext to Document With this change, elements that want to receive viewport rect updates will need to register on document instead of the browsing context. This change solves the problem where a browsing context for a document is guaranteed to exist only while the document is active so browsing context might not exit by the time DOM node that want to register is constructed. This is a part of preparation work before switching to navigables where this issue becomes more visible.

LibWeb: Make CSS layout lazier Instead of doing layout synchronously whenever something changes, we now use a basic event loop timer to defer and coalesce relayouts. If you did something that requires a relayout of the page, make sure to call Document::set_needs_layout() and it will get coalesced with all the other layout updates. There's lots of room for improvement here, but this already makes many web pages significantly snappier. :^) Also, note that this exposes a number of layout bugs where we have been relying on multiple relayouts to calculate the correct dimensions for things. Now that we only do a single layout in many cases, these kind of problems are much more noticeable. That should also make them easier to figure out and fix. :^)

LibWeb: Bring browsing context creation closer to spec This patch implements the "create a new browsing context" function from the HTML spec and replaces our existing logic with it.

This makes it possible for websites to create a new iframe and start scripting inside it right away, without having to load an URL into it.

LibWeb: Cache the first <base href> (in tree order) in Document When parsing relative URLs, we have to check the first <base href> in tree order (if one is available). This was getting *very* costly on large DOMs with many relative urls. This patch avoids all that repeated traversal by letting Document cache the first <base href> and invalidating the cache whenever a <base> element is added/removed/edited in the DOM. The browser was stuck doing this for a *very* long time when loading the ECMA-262 spec, and this removes that problem entirely.

LibWeb: Don't parse inline style sheets during HTML fragment parsing Some websites (like Reddit) like to instantiate "components" by setting innerHTML to a huge chunk of stuff. Sometimes those huge chunks of stuff contain inline style sheets (i.e `<style>` elements). Before this change, we would end up parsing the CSS in those elements multiple times, because we had no way of knowing that we were within a fragment parser's temporary document. This patch avoids the extra CSS parsing work by adding adding a flag to Document that tells us it's being used by the fragment parser. Then, we simply avoid parsing CSS for style elements in such documents. The CSS then gets parsed immediately upon insertion into the proper DOM.

LibWeb: Forbid sharing image requests across documents This change addresses the bug where images unable to load when the reload button in the UI is clicked repeatedly. Before this fix, it was possible to use SharedImageRequests across multiple documents. However, when the document that initiated the request is gone, tasks scheduled on the event loop remain in the fetching state because the originating document is no longer active. Furthermore, another reason to prohibit the sharing of image requests across documents is that the "Origin" header in an image request is dependent on the document.
