This means that an `<input type=password>` will show the correct number
of *s in it when non-ASCII characters are entered.
We also don't need to perform text-transform on these as that doesn't
affect the output length, so I've moved it earlier.
After we absolutize the contents of :has(), we check that those child
selectors don't contain anything that :has() rejects.
This is a separate path than the checks inside the parser, which is
unfortunate.
Fixes a WPT ref test. :^)
It's possible for absolutizing a selector to return an invalid selector
(eg, it could cause `:has()` inside `:has()`) so we need to be able to
express that.
The CSSOM spec tells us to potentially add up to three different IDL
attributes to CSSStyleDeclaration for every CSS property we support:
- A camelCased attribute, where a dash indicates the next character
should be uppercase
- A camelCased attribute for every -webkit- prefixed property, with the
first letter always being lowercase
- A dashed-attribute for every property with a dash in it.
Additionally, every attribute must have the CEReactions and
LegacyNullToEmptyString extended attributes specified on it.
Since we specify every property we support with Properties.json, we can
use that file to generate the IDL file and it's implementation.
We import it from the Build directory with the help of multiple import
base paths. Then, we add it to CSSStyleDeclaration via the mixin
functionality and inheriting the generated class in
CSSStyleDeclaration.
This allows us to specify multiple base paths to look for imported IDL
files in. This will allow us to import IDL files from sources and from
the Build directory (i.e. for generated IDL files).
We currently have 2 virtual methods to inform DOM::Element subclasses
when an attribute has changed, one of which is spec-compliant. This
patch removes the non-compliant variant.
Instead, smuggle it in as a `void*` private data and let Javascript
aware code cast out that pointer to a VM&.
In order to make this split, rename JS::Cell to JS::CellImpl. Once we
have a LibGC, this will become GC::Cell. CellImpl then has no specific
knowledge of the VM& and Realm&. That knowledge is instead put into
JS::Cell, which inherits from CellImpl. JS::Cell is responsible for
JavaScript's realm initialization, as well as converting of the void*
private data to what it knows should be the VM&.
NanBoxedValue is intended to be a GC-allocatable type which is not
specific to javascript, towards the effort of factoring out the GC
implementation from LibJS.

This time, set up a different combinator when producing a relative
invalid selector rather than a standalone one. This fixes the crash.
Original description below for simplicity because it still applies.

Selectors like `:is(.valid, &!?!?!invalid)` need to keep the invalid
part around, even though it will never match, for a couple of reasons:
- Serialization needs to include them
- For nesting, we care if a `&` appeared anywhere in the selector, even
in an invalid part.
So this patch introduces an `Invalid` simple selector type, which simply
holds its original ComponentValues. We search through these looking for
`&`, and we dump them out directly when asked to serialize.
This gets rid of a couple FIXMEs and allows reusing the logic of
validating this field between different algorithms. While we're here,
expand its logic to match the constraints as outlined in RFC 7517.
LibWebView now knows how to launch RequestServer and ImageDecoderServer
without help from the UI, so let's move ownership of these services over
to LibWebView for de-duplication.
This was a silly mistake on my end and percentages values are not
covered by device-independent color space, so I had to add support for
srgb to run a WPT test that made me realize the mistake.
This makes the following test pass:
- css/css-color/predefined-002.html
It makes the following WPT tests pass:
- css/css-color/predefined-001.html
- css/css-color/xyz-003.html
- css/css-color/xyz-d50-003.html
- css/css-color/xyz-d50-004.html
- css/css-color/xyz-d65-003.html
Also we now render the reference of color-mix-currentcolor-nested-for-
color-property.html properly. Which means that it's now different from
the actual test, that is still rendered incorrectly. In other word, the
false positive for this test is now turned into a true negative.
Now that the heap has no knowledge about a JavaScript realm and is
purely for managing the memory of the heap, it does not make sense
to name this function to say that it is a non-realm variant.
The main motivation behind this is to remove JS specifics of the Realm
from the implementation of the Heap.
As a side effect of this change, this is a bit nicer to read than the
previous approach, and in my opinion, also makes it a little more clear
that this method is specific to a JavaScript Realm.

We will want to re-inform WebContent of the system visibility state when
we create a new process after a crash. This changes the IPC to just send
the enum value directly, instead of a boolean, so that we can just store
that enum value directly on the ViewImplementation class.
These operations should still apply even if they are off screen, because
they affect painting of things outside of their bounding rectangles.
This commit makes us always apply these, regardless of if they are in
the visible region. However, if they are outside that region, we
replace them with simple clip-rect commands, which have the same
effect (not painting anything) but are cheaper than computing a full
mask bitmap.
The insertion steps for iframes were following an old version of the
spec, where it was checking if the iframe was "in a document tree",
which doesn't cross shadow root boundaries. The spec has since been
updated to check the shadow including root instead.
This is now needed for Cloudflare Turnstile iframe widgets to appear,
as they are now inserted into a shadow root.
Previously, the inclusive descendant, which is the node that
for_each_shadow_including_inclusive_descendant was called on, would not
have it's shadow root traversed if it had one.
This is because the shadow root traversal was in the `for` loop, which
begins with the node's first child. The fix here is to move the shadow
root traversal outside of the loop, and check if the current node is an
element instead.
