We were hard-coding "about:blank" as the document URL for parsed HTML
documents, which was definitely not correct.
This fixes a bunch of WPT tests under /domparsing/ :^)
This resolves all WPT timeouts in html/canvas/element/manual/imagebitmap
We can now run an additional 6 tests and 126 subtests :)
This also adds regression tests for this behavior.
InlinePaintable was an ad-hoc paintable type required to support the
fragmentation of inline nodes across multiple lines. It existed because
there was no way to associate multiple paintables with a single layout
node. This resulted in a lot of duplicated code between PaintableBox and
InlinePaintable. For example, most of the CSS properties like
background, border, shadows, etc. and hit-testing are almost identical
for both of them. However, the code had to be duplicated to account for
the fact that InlinePaintable creates a box for each line. And we had
quite many places that operate on paintables with a code like:
```
if (box.is_paintable_box()) {
// do something
} else (box.is_inline_paintable()) {
// do exactly the same as for paintable box but using InlinePaintable
}
```
This change replaces the usage of `InlinePaintable` with
`PaintableWithLines` created for each line, which is now possible
because we support having multiple paintables per layout node. By doing
that, we remove lots of duplicated code and bring our implementation
closer to the spec.
Always create a new formatting context for <math> elements. Previously
that didn't happen if they only had inline children, e.g. mtable.
This fixes a crash in the WPT MathML test

Ignoring the fact that we should serialize a simplified form of calc()
expressions, the following are wrong:
- grid-auto-columns
- grid-auto-rows
- grid-template-columns
- grid-template-rows
- transform-origin
Generated in part with this python script (though I've since iterated on
the output repeatedly so it's quite different):
```py
import json
properties_file = open("./Userland/Libraries/LibWeb/CSS/Properties.json")
properties = json.load(properties_file)
for (key, value) in properties.items():
if not 'valid-types' in value:
continue
if 'longhands' in value:
continue
valid_types = value['valid-types']
for type_string in valid_types:
name, *suffix = type_string.split(None, 1)
match name:
case 'integer' | 'number':
print(f'{key}: calc(2 * var(--n));')
case 'angle':
print(f'{key}: calc(2deg * var(--n));')
case 'flex':
print(f'{key}: calc(2fr * var(--n));')
case 'frequency':
print(f'{key}: calc(2hz * var(--n));')
case 'length':
print(f'{key}: calc(2px * var(--n));')
case 'percentage':
print(f'{key}: calc(2% * var(--n));')
case 'resolution':
print(f'{key}: calc(2x * var(--n));')
case 'time':
print(f'{key}: calc(2s * var(--n));')
```
Previously we would serialize these as the empty string. eg, this:
```
<div style="grid-auto-columns: auto"></div>
```
would have a computed `grid-auto-columns` value of ``.

Invalidating the style here means that transitions can cause an element
to leave style computation with its "needs style update" flag set to
true. This then causes a VERIFY to fail in the TreeBuilder.
This invalidation does not otherwise seem to have any effect. The
original commit suggests this was to fix a bug, but it's not clear what
bug that was. If it reappears, we can try to solve the issue in a
different way.
Cookies have a minimum expiry resolution of 1 second. So to test cookie
expiration, the test had to idle for at least a second, which is quite a
noticeable delay now that LibWeb tests are parallelized.
Instead, we can add an internal API to expire cookies with a time offset
to avoid this idle delay.
Previously Selection.extend() used only the relative node order to decide which
direction to extend the selection. This leads to incorrect behaviour if
both the existing and new boundary points are within the same DOM node
and the selection direction is reversed.
This change fixes all the failing subtests in the WPT extend-* test
suites.
DedicatedWorkerGlobalScope is an object with a Global extended
attribute, but does not define any named property getters. This needs to
be handled by setting the prototype chain to:
DedicatedWorkerGlobalScope
^ DedicatedWorkerGlobalScopePrototype
^ WorkerGlobalScopePrototype
(This is different from something like Window, where there is an
intermediate WindowProperties object for named properties.)
Previously, we treated the GlobalMixin object as if it was a simple
prototype object, accidentally setting DedicatedWorkerGlobalScope's
prototype to WorkerGlobalScopePrototype. This caused the expression
self instanceof DedicatedWorkerGlobalScope
to return false inside workers.
This makes us pass many more of the "/xhr/idlharness.any.worker" WPT
tests than before, rather than failing early.
The "isCollapsed" attribute on a selection must "return true if and only
if the anchor and focus are the same".
In addition to checking that the anchor and focus belonged to the same
DOM node, we now also check that they refer to the same position within
the node.
With this change Ladybird passes all the subtests in the "isCollapsed"
WPT suite.

The video was accidentally removed in commit d5ba665f89.
This adds the video back to the LibWeb/Text/data folder, and validates
that the video loads in the test that depends on it loading.
We have support for using (shift+)tab to move focus to the next/previous
element on the page. However, there were several ways for this to crash
as written. This updates our implementation to check if we did not find
a node to move focus to, and to reset focus to the first/last node in
the document.
This doesn't seem to work when wrapping around from the first to the
last node. A FIXME has been added for that, as this would already not
work before this patch (the main focus here is not crashing).
Our handling of left vs. right modifiers keys (shift, ctrl, etc.) was
largely not to spec. This patch adds explicit UIEvents::KeyCode values
for these keys, and updates the UI to match native key events to these
keys (as best as we are able).
The spec expects `postMessage()` to act as if it is invoked
immediately. Since `postMessage()` isn't actually invoked immediately,
keep tasks with source `PostedMessage` in the task queue, so that these
tasks are processed. Fixes a hang when `WorkerGlobalScope.close()` is
called immediately after `postMessage()`.

Add idl, header and stubs for PerformanceEventTiming interface.
Two missing `PerformanceEntry` types that have come up in issues
are the `first-input` and the `event` entryTypes. Those are both
this.
Also, because both of those are this same interface, the static
methods from the parent class are difficult to implement because
of instance-specific details. Might either need subclasses or to
edit the parent and also everything that inherits from it :/
This test caused some flakiness due to the about:blank load it triggers.
It causes headless-browser to receive a load event for about:blank. If
we have moved onto the next test before that event arrived, that test
would ultimately time out, as its own load will have been dropped while
the about:blank load is still ongoing.
This patch makes us wait for that iframe load event before completing
the test.
We may want to consider never sending subframe load events to the UI
process as well. We really only care about top-level page loads in the
receivers of that event.
