To update to ICU 78.1, a bump to the Vcpkg baseline is required.
However, for some reason 1.3.0#0 fails to compile on the newer
baseline. Updating to 1.3.0#1 fixes the issue.
The m_last_match, m_left_context, and m_right_context views were being
created from a temporary string instead of from the owned m_input.
This caused the views to point to destroyed stack memory when accessing
RegExp.lastMatch after calling String.replace() with a regex.
From the spec:
> The owning element of a transition refers to the element or
pseudo-element to which the transition-property property was applied
that generated the animation.

Previously we only stored the element.
This patch adds an API for posting a Core::Event::Type to the thread
event queue without requiring a full Core::Event object.
We use this API to avoid heap allocations for every timer and notifier
activation event.
If a script on the page cancels a mousemove event, we would return early
and neglect to update the cursor. This is seen regularly on "Diablo Web"
where they set the cursor to "none" on the main canvas, and also cancel
mousemove events.
Our existing implementation was checking if the generator step result
was `undefined` to indicate that the generator is complete. This is
not sufficient for an upcoming implementation of Iterator.concat, where
`undefined` is used as an incomplete iteration result.
Instead, let's have the Iterator prototype return an IterationResult to
explicitly indicate its completeness. As a result, the prototype also
looks more like the spec now.
The DeferredInvocationContext only existed to satisfy the requirement
in ThreadEventQueue that each event has an EventReceiver. However,
deferred_invoke() was not even using the EventReceiver to call its
callback. Therefore, we don't need to allocate one for every deferred
invocation.
This also prevents WeakPtr::strong_ref() from racing and leaking the
context object when invoking a function across threads.
For some reason, it seems that passing NonnullRefPtr<SeekData> const&
was causing us to triple ref() in the capture group for the audio seek
handlers, followed by only a single unref(). Changing this to plain old
SeekData& inexplicably fixes the leak.
This enables the disk cache and flips the related command line flag to
allow disabling it. We've reached a point where it works well, so this
will let us get more mileage on it.
Fixes some WPT tests that expected `supports(foo:bar)` to serialize as
`supports(foo:bar)`, instead of `supports(foo: bar)` with a space
between.
Reading the original_full_text directly also lets us delete
Declaration::to_string(), which was only used here.
In some situations we want to examine a sequence of tokens that have
been already consumed from a TokenStream. These methods let us do so:
- current_index() provides the current internal token index
- tokens_since() provides a span from the given index to the current one
The previous implementation assumed that the contents of `supports()`
was either a raw declaration, or a block containing some number of them.
This meant we wouldn't parse things like `supports(not (a:b))` or
`supports(selector(*))`.
`parse_a_supports()` actually does what we want in every case except for
raw declarations (`supports(a: b)`), so let's always call it first, and
then fall back to parsing a single declaration.
