This is enough for Firefox to display the Accessibility tab, containing
our accessibility tree which can be inspected. Most information is
blank for now.
There's quite a bit of duplication between AccessibilityWalkerActor and
WalkerActor - it might be worth trying to make a base class once the
details are figured out. Frustratingly, the two don't work quite the
same: for a lot of messages that would be sent to WalkerActor, the
accessibility equivalent is sent to the AccessibilityNodeActor instead.

Since memory64 got merged into the spec the minimum value for limits
is now actualy 64-bit and the maximum sizes for memories and tables
for I64 address types were increased.
Fixes 5 tests in memory64.wast nad 8 tests in table64.wast on WPT.
Otherwise the layout tree will still contain the top layer element(s).
Fixes Steam Events & Announcements `<dialog>` modal visually not fully
disappearing upon removal.
In some cases a document may lack an associated window - to fix this for
now we just return false but perhaps there are some media queries we
should still attempt to resolve.
This is a weak pointer that integrates with the garbage collector.
It has a number of differences compared to AK::WeakPtr, including:
- The "control block" is allocated from a well-packed WeakBlock owned by
the GC heap, not just a generic malloc allocation.
- Pointers to dead cells are nulled out by the garbage collector
immediately before running destructors.
- It works on any GC::Cell derived type, meaning you don't have to
inherit from AK::Weakable for the ability to be weakly referenced.
- The Weak always points to a control block, even when "null" (it then
points to a null WeakImpl), which means one less null check when
chasing pointers.
Let's have a way to run all the JavaScript the web wants to give us.
This was previously available as a Debug menu option, and this makes
it available from process startup.
IDBGetAllOptions is supposed to have a default value for direction.
When the value passed is not a potentially valid key range, we
need to default the direction argument, and not assume its set

This commit implements support for forward references to named capture
groups. We now allow patterns like \k<name>(?<name>x) and
self-references like (?<name>\k<name>x).
Previously, named capture groups in RegExp results did not always follow
their source order, and unmatched groups were omitted. According to the
spec, all named capture groups must appear in the result object in the
order they are defined, even if they did not participate in the match.
This commit makes sure we follow this requirement.
Fixes handling of backreferences when the referenced capture group is
undefined or hasn't participated in the match.
CharacterCompareType::NamedReference is added to distinguish numbered
(\1) from named (\k<name>) backreferences. Numbered backreferences use
exact group lookup. Named backreferences search for participating
groups among duplicates.
If transferring a cached response body fails for any reason, we will now
issue a network request instead of failing the request outright.
The catch here is that we will have already transferred the response
code and headers to the client, and potentially some of the body. So we
attempt to only request the remaining data over the network using a
range request. This feels a bit sketchy, but this is also how Chromium
behaves.
However, the server may or may not support range requests. If they do,
we can expect an HTTP 206 response with the bytes we need. If not, we
will receive an HTTP 200 (assuming the request succeeded), along with
the entire object's body. In this case, we also behave like Chromium,
and internally drop number of bytes we had already transferred.
If we are unable to pipe the response body from a cache file to the
client, let's take the extra safe approach of deleting the cache file
for now. We already remove the file if we weren't able to read its
metadata during initialization.
Previously these were only stored on the root style sheet and were
accessed by imported stylesheets via their owner rule.
Propagating these to imported style sheets allows us to more easily know
when they change for said imported style sheets.
Some documents (e.g. those created by DOMParser.parseFromString()) will
not be associated with a navigable. These documents effectively have a
viewport of 0x0.
- Add FLATTEN (same as we do for internal_call()).
- Demote nice-to-have VERIFYs to ASSERTs.
- Pass already-known Realm to ordinary_create_from_constructor
1.03x speedup on Octane/earley-boyer.js
We should invert CMYK data only if color space is JCS_CMYK and either
there is no Adobe marker, or the Adobe transform is 0. Transform 2
indicates YCCK data, which we should not invert.
Make WindowProxy implement the EventTarget interface. Add a new method
current_target_for_bindings() that returns a WindowProxy object instead
of directly exposing the Window object.
These changes fixes several WPT tests that contain `window ===
currentTarget`.
