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));')
```

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()`.
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.

Spinning the event loop was causing a crash on:
https://wpt.live/url/percent-encoding.window.html
As it was turning what is meant to be a synchronous operation into an
asynchronous one.
The sequence demonstrated by the reproducing test is as follows:
* A src attribute is changed for the iframe
* process_the_iframe_attributes entered with valid content navigable
* Event loop is spun, allowing the queued iframe removal to execute
* process_the_iframe_attributes continues with null content navigable
* 💥
Because of the previous awkward factoring of Origin we had two
implementations of Origin serializing and creation. Move the
implementation of DOMURL::url_origin into URL::origin, and
instead use the implemenation of URL::Origin::serialize for
serialization (replacing URL::serialize_origin).
This happens to fix 8 URL subtests as the two implemenations had
diverged, and URL::serialize_origin was previously missing the spec
changes of: whatwg/url@eee49fd and whatwg/url@fff33c3
Previously, if there was an unhandled exception in an async test, it
might fail to call done() and timeout. Now we have a default "error"
handler to catch unhandled exceptions and fail the test. A few tests
want to actually test the behavior of window.onerror, so they need an
escape hatch.
Before this change we were serializing them in a bogus 8-digit hex color
format that isn't actually recognized by HTML.
This code will need more work when we start supporting color spaces
other than sRGB.
Now we can register jobs and they will be executed on the event loop
"later". This doesn't feel like the right place to execute them, but
the spec needs some updates in this regard anyway.
Fixes at least one WPT test that was previously timing out:
