Previously the input element was displayed with value 0, when no value
was set in the HTML. Now it uses `value_sanitization_algorithm()`, which
will calculate the default value.
In `value_sanitization_algorithm()` there was a logical mistake/typo.
The comment from the spec says "unless the maximum is less than the
minimum".
The added layout test would fail without the code changes.
Fixes#520
When the min option is given the read will only be fulfilled when there
are min or more elements available in the readable byte stream.
When the min option is not given the default value for min is 1.
The first time Document learns its viewport size, we now suppress firing
of the resize event.
This fixes an issue on multiple websites that were not expecting resize
events to fire so early in the loading process.
Previously, setting CSS `line-height: 0` on an `input` element would
result in no text being displayed.
Other browsers handle this by setting the minimum height to the
"normal" value for single line inputs.
From https://html.spec.whatwg.org/multipage/scripting.html#script-processing-model:
When a script element el that is not parser-inserted experiences one
of the events listed in the following list, the user agent must
immediately prepare the script element el:
- [...]
- The script element is connected and has a src attribute set where
previously the element had no such attribute.
Previously, when `WindowOrWorkerGlobalScope.reportError()` was called
the `filename` property of the dispatched error event was blank. It is
now populated with the full path of the active script.
Like 1132c858e9, out-of-flow elements such
as float elements would get inserted into block level `::before` and
`::after` pseudo-element nodes when they should instead be inserted as a
sibling to the pseudo element. This change fixes that.
This fixes a few layout issues on the swedish tax agency website
(skatteverket.se). :^)
This makes it so that `rebaseline-libweb-test` can be run on *nix or
MacOS as the path to `headless-browser` on MacOS is
`./bin/Ladybird.app/Contents/MacOS/headless-browser` while it is
`./bin/headless-browser` on *nix.
Following the rules in the algorithm from
https://webidl.spec.whatwg.org/#js-platform-objects, "To Internally
create a new object implementing the interface interface", this change
incorporates the steps to load a prototype from new.target, and write
it to the created instance returned from constructor_impl(). This
mirrors the code for generate_html_constructor(), which incorporates
additional steps needed by Custom Elements.
Bug #334
This is a non-standard API that other browsers implement, which
highlights matching text in the current window.
This is just a thin wrapper around our find in page functionality, the
main motivation for adding this API is that it allows us to write tests
for our find in page implementation.
If a flex item has a preferred aspect ratio and the flex basis is not
definite, we were falling back to using stretch-fit for the main size,
since that appeared to match other browsers.
However, we missed the case where we actually have a definite cross size
through which the preferred aspect ratio can be naturally resolved.
To get away from the ancient (and buggy) text layout code in
Gfx::Painter, we want to remove all the uses of Painter::draw_text().
As a first step towards this, we implement the draw_text() display list
command in terms of the draw_text_run() command by performing the very
simple necessary layout in draw_text() beforehand.
The values aren't that complex, so it doesn't make much sense to have a
dedicated generator for them. Parsing them manually also allows us to
have much more control over the produced values, so as a result of this
change, EasingStyleValue becomes much more ergonomic.
...and shadow tree with TextNode for "value" attribute is created.
This means InlineFormattingContext is used, and button's text now
respects CSS text-decoration properties and unicode-ranges.
The main intention of this change is to have a consistent look and
behavior across all scrollbars, including elements with
`overflow: scroll` and `overflow: auto`, iframes, and a page.
Before:
- Page's scrollbar is painted by Browser (Qt/AppKit) using the
corresponding UI framework style,
- Both WebContent and Browser know the scroll position offset.
- WebContent uses did_request_scroll_to() IPC call to send updates.
- Browser uses set_viewport_rect() to send updates.
After:
- Page's scrollbar is painted on WebContent side using the same style as
currently used for elements with `overflow: scroll` and
`overflow: auto`. A nice side effects: scrollbars are now painted for
iframes, and page's scrollbar respects scrollbar-width CSS property.
- Only WebContent knows scroll position offset.
- did_request_scroll_to() is no longer used.
- set_viewport_rect() is changed to set_viewport_size().
The DocumentTimeline constructor used the current millisecond time to
initialize its currentTime, but that means that a newly created timeline
would always have a different time value than other timelines that have
been through the update_animations_and_send_events function.
`Painting::paint_all_borders()` only uses `.draw_line()` for simple
borders and `.fill_path()` for more complex cases. These are both
already supported by the `RecordingPainter` so removing this command
simplifies the painting API.
Two test changes:
css-background-clip-text: Borders are now drawn via the AA painter
(which makes them closer to how they appear in other browsers).
corner-clip-inside-scrollable: Borders removed (does not change test)
due to imperceptible sub-pixel changes.
Previously, we always cast to a HTMLInputElement when getting the value
of an auto directionality form associated element. This caused
undefined behavior when determining the directionality of an element
that wasn't a HTMLInputElement.
Previously, we assumed that all label control paintables were of type
`LabelablePaintable`. This caused a crash when clicking on a label with
a text input control.
This initializes 'arrayBuffer' to an UInt8Array so that we can
manipulate the contents of 'arrayBuffer'. The test verifies that the
internal buffer is an ArrayBuffer.
Also:
* Correct comparison in test so that we compare arrayBuffer to
arrayClone, not to itself.
* Remove FIXME, this outputs [object ArrayBuffer] in Firefox and Chrome
too.
All painting commands except SetClipRect are shifted by scroll offset
before command list execution. This change removes scroll offset
translation for sample/blit corner commands in
`PaintableWithLines::paint` so it is only applied once in
`CommandList::apply_scroll_offsets()`.
The if statement in the dispatch implies we are in the idle state, so of
course the active time will always be undefined. If this was cancelled
via a call to cancel(), we can save the time at that point. Otherwise,
just send 0.
This patch fixes two issues:
- Animation events that should go to the target element now do
(some were previously being dispatched on the animation itself.)
- We update the "previous phase" and "previous iteration" fields of
animation effects, so that we can actually detect phase changes.
This means we stop thinking animations always just started,
something that caused each animation to send 60 animationstart
events every second (to the wrong target!)
This change adds the `width` and `height` properties to
`HTMLVideoElement` and `HTMLSourceElement`. These properties reflect
their respective content attribute values.
This returns the secondary target of a mouse event. For `onmouseenter`
and `onmouseover` events, this is the EventTarget the mouse exited
from. For `onmouseleave` and `onmouseout` events, this is the
EventTarget the mouse entered to.
For now, this slot is always 0 - (the default value per spec). But
once we start actually processing audio streams this internal slot
should be changed correspondingly.
We are often trying to click the image before it has finished loading.
This results in us trying to click a 0x0 rect. Instead, wait until the
image load event.
This fixes a flake with form-image-submission.html often seen on CI.
The spec isn't _super_ clear on how this is meant to be done, but the
way I understand this is that we should simply clamp the returned
'current value' between 'min' and 'max'.
Firefox does not appear to do this clamping, but Chrome does.
This is a simple getter and setter of the OscillatorType enum, with
error checking to not allow 'custom', as that should only be changed
through 'setPeriodicWave()'.
This is still missing a bunch of spec steps to construct the
audio node based on the parameters of the OscillatorNode, but it is at
least enough to construct an object to be able to add a basic test which
can get built upon as more is implemented.
Previously, we would apply any adopted style sheet to the document if
its alternate flag was not set. This meant that all adopted style
sheets would be applied, since constructed style sheets never have this
flag set.
Previously, [Global] interfaces were not excluded from the
`internal_own_property_keys()` call. This caused a crash when iterating
over the properties of the Window object.
Fixes bug when CSS transform is applied twice to clip rect:
- While calculating absolute clip rectangles in `refresh_clip_state()`
- While executing `PushStackingContext` painting command.
Duplicated transform is already removed for PaintableBox and this change
adds this for InlinePaintable.
Previously we would look for a matching ID, and then for a matching
name. If there was an element in the collection which had a matching ID
as well as an element with a matching name, we would always return the
element with a matching ID irrespective of what order that element was
in.
Otherwise, the thread will continue to run and access the media data
buffer, which will have been freed.
The test here is a bit strange, but the issue would only consistently
repro after several GC runs.

The problem was `navigable` null pointer dereferencing in
`decode_favicon()`. But navigable is null because the document was
created by `parseFromString()` DOMParser API.
With this change we skip fetching initiated by HTMLLinkElement if
document does not have a browsing context:
- Favicon is not displayed for such documents so no need to fetch.
- Stylesheets fetching won't affect such document because style or
layout does not run for them.
The HTMLLinkElement caller is a bit hairy, so we shove an await() in
there temporarily. This is sure to cause fun times for anyone debugging
task/microtask execution order.
We have to unregister link element stylesheets from the old document's
StyleSheetList when moving them into a new document.
This makes it possible to load GitHub contributor graphs. :^)
We can't rely on Element.setAttribute() in cloneNode() since that will
throw on weird attribute names. Instead, just follow the spec and copy
attributes into cloned elements verbatim.
This fixes a crash when loading the "issues" tab on GitHub repos.
They are actually sending us unintentionally broken markup, but we
should still support cloning it. :^)
Seems like a specification bug, but other browsers update url before
popstate event is fired and so should we.
Fixes back/forward navigation on GitHub.
This fixes a regression on Acid3, since we are not expected to "best
effort" parse XML. The test specifically checks that you don't create an
incomplete, incorrect DOM.
This line changes padding top to align cell content to baseline:
`cell.padding_top += m_rows[cell.row_index].baseline - cell.baseline`
Which means available for distribution height `height_diff` could have
changed so it needs to be refreshed before assigning the rest of it to
padding bottom:
`cell_state.padding_bottom += height_diff;`
Fixes https://github.com/SerenityOS/serenity/issues/22032
When loading an XML resource into an iframe and the resource fails to
decode (e.g due to invalid UTF-8), we must still fire a load event.
This fixes the regression in subtest 69 of Acid3.
Navigation should not run for <object> element until it is inserted into
a document. Spec deoes not seem to explicitely say that, but that
matches other browsers behavior.
Fixes hanging after reloading in Acid3 test.
There were two things going wrong here:
- Transformed text (via CSS text-transform) was not invalidated after a
`@media` rule changed state.
- Removing the `style` attribute from an element didn't trigger a style
update.
This fixes the regression in subtest 46 of Acid3.
Fixes#21777
