Rather than modify the transform of the parent (which could change
independently), this adds a new override element_transform() where
element specific tranfroms can be applied. This will always stay in
sync with the attributes.
A ref test comparing a .svg and .html version of the same file is
added as due to differences in attribute parsing order, the .svg version
was previously drawn incorrectly.
Fixes#20859
Promises can take an Error type now for quite some time, so let's use it
instead of returning an empty Optional type in the result field. :^)
Ideally we should give a more detailed info of what failed to parse, but
this will do for now.
None of the existing tests contain a URL which has a fragment in them,
but this does verify that the URL parser does not actually find any!
Also, this should let us verify the correctness of URLs which actually
do contain fragments.
This part of the spec is mostly useful for our debugging for now, but
could eventually be hooked up so that the user can see any reported
validation errors.
The main change here is that we now follow the spec by asserting the URL
is not special. Previously I could not find a way to enable this without
getting assertions when browsing the web - but that seems to no longer
be the case (probably from some other fixes which have since been made).
Previously, we always assumed that local includes are relative to the
parent directory of a file. This effectively banned style-wise
multi-directory subprojects which are not libraries, since there was no
way to cleanly reference local file from a different directory.
This commit relaxes the restrictions by introducing
LOCAL_INCLUDE_ROOT_OVERRIDES. Entry in the set changes root of the
local includes to itself for all files in its subtree.
Previously, the corner overlap algorithm implementation did not shrink
the border radii for zero width/height boxes, which resulted in
incorrect painting.
With this the implementation is updated to more closely follow the spec
steps, which naturally handles the zero width/height case. This makes
use of the `CSSPixelFraction` class for lossless comparison and
multiplication of the scaling factor for the radii.

This class will allow us to compare the ratio of two `CSSPixels` values
losslessly.
Not only that, but an operation like `a * (b / c)` should no longer
be lossy, since the operation can be carried out as `(a * b) / c`
implicitly instead.
Since we always pass the px value as an argument to resolved(), we can
pass it directly as CSSPixels instead of wrapping it in Length. This
approach allows us to avoid converting to a double, resulting in fewer
precision issues.
If we set m_waiting_for_messages to true for the intial message request,
we might never receive a response, and block the console from requesting
any more messages indefinitely. Instead, issue a non-blocking initial
request, which is how the Qt and Serenity chromes behaved before the
ConsoleClient abstraction.
This also changes ConsoleClient::clear() to use run_javascript() rather
than js_console_input(), as that is also how the chromes used to behave.
This adds menu items to open an interactive JavaScript console for a web
page. This more or less mimics the Qt implementation of the console.
Hooks are included to tie the lifetime of the console window with the
tab it belongs to; if the tab is closed, the console window is closed.
This creates WebView::ConsoleClient to handle functionality that will be
common to the JS consoles of all Ladybird chromes. This will let each
chrome focus on just the UI.
Note that this includes the `console.group` functionality that only the
Serenity chrome previously had. This was a FIXME in the Qt chrome, and
it is implemented such that all chromes will receive this functionality
for free.
The LadybirdWebView currently assumed it is viewed with a Tab instance.
This will not be true with the JavaScript console. This patch removes
this assumption by plumbing WebContent callbacks through a new protocol.
The Tab interface then implements this protocol.
For example, the JavaScript console will invoke window.scrollTo(0, INF)
to scroll to the bottom of the console after updating its contents. The
NSScrollView being scrolled here seems to behave oddly if we scroll
beyond its limit (e.g. mouse events stop working). Prevent this by
limiting scrolling to the NSScrollView's document rect.
We were relying on TabController setting the web view's initial viewport
in [TabController windowDidResize], which has been triggered when the
Tab is first created. However, it turns out that only happens due to the
toolbar being added to the Tab window, causing a resize event. When the
web view is embedded in a window without a toolbar, this resize event is
not triggered. Therefore, we must set the viewport ourselves when the
web view is added to a window.
All SQL callbacks here were already moving the to-be-executed callback
out of its storage before executing it, except for on_next_result().
This makes on_next_result() do the same move to ensure we do not later
attempt to move it while the callback is executing.
This is not we're supposed to do according to https://tc39.es/ecma262/#sec-runtime-semantics-propertydefinitionevaluation
Furthermore, this was observable by ToPrimitive looking up toString and
valueOf and potentially calling them if they exist. The big ticket
issue however is that for objects without toString and valueOf, such as
null-proto objects, this would unexpectedly throw.
When text paintables shift around in the tree due to line wrapping,
we may end up in a situation where some text node does not generate
a paintable (due to being all whitespace, for example), even though
in the previous layout pass, it *did* generate a paintable.
To prevent holding on to old paintables in such cases, we now do a
pass in LayoutState::commit() where we explicitly detach all old
paintables from the layout tree.
