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 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.

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.
This was preventing https://ubereats.com/ from fully loading, because
they are attempting to overwrite setItem. They seem to be trying to add
error logging to setItem if it throws, as all they do is add a
try/catch block that emits an error log to their monitoring service if
it throws.
However, because Storage is a legacy platform object with a named
property setter (setItem), it will call setItem with the stringified
version of the function. This is actually expected as per the spec,
Firefox (Gecko) and Epiphany (WebKit) does this too, but Chromium does
not as it actually overwrites the function with the new function and
does not store the stringified function.
The problem is that we had the LegacyOverrideBuiltIns flag accidentally
set, so it would return the stored string instead of the built-in
function (hence the name), then it would try and call it and throw a
"not a function" error. This prevented their JS from going any further.
This fix allows their UI to fully load and be fully interactive, though
it is quite slow at the moment!
The example shows how to write a test that depends on custom HTTP
headers in the response. This will be useful for testing browser JS
that depends on how Ladybird processes response headers, eg CORS
headers like Access-Control-Allow-Origin and others.
This change fixes accessible-name computation for:
- an element that has empty text content but that also has a title
attribute (“tooltip”) with a non-empty value
- an img element whose alt attribute is the empty string but that also
has a “title” attribute with a non-empty value
Otherwise, without this change, the accessible name unexpectedly isn’t
computed correctly for those cases.
A few are skipped for now:
- A few ref tests fail
- Crash tests are not supported by our runner and time out
- top-level-is-scope.html crashes and needs further investigation
This causes 36 new subtests to pass locally. :^)
Unfortunately at least one of these is flaky when it's able to load the
font file, apparently because we don't wait for the font and its
stylesheet to actually load before the tests run.
Range API uses UTF-16 code units to represent offsets, so replace_data()
needs to use it instead of bytes count while calculating new offsets.
Fixes incorrectly thrown exception when non-latin string is passed into
replace_data().
This is enough for a basic shadow realm to work :^)
There is more that we still need to implement here such as module
loading and fixing up the global object, but this is enough to get some
basic usage working.
If the attribute value is the empty string `(lang="")`, the language
is set to unknown. `lang` attribute higher up in the document tree
will no longer be applied to the content of that element.
We guarded one step against a null navigable, but the very next step
also needs to be protected. Let's just abort early instead. This was
caught by the following imported WPT test:
html/dom/elements/the-innertext-and-outertext-properties/innertext-setter.html
This test adds a <frame> element and immediately removes it, but the
task to process the src attribute is already queued. Note that <iframe>
would have the same issue, but this test does not include them.
NavigableContainer is our home grown concept which already contains the
AOs needed for frame and iframe elements. This patch simply aligns our
HTMLFrameElement implementation with this class.
A couple of notes:
1. The <script> in the <head> element is intentional. The <frameset>
element effectively takes the place of the <body> element, and we
cannot add a <script> to a <frameset> element.
2. We don't render <frameset> or <frame> at all. Rendering is defined
in the following spec:
https://html.spec.whatwg.org/multipage/rendering.html#frames-and-framesets
3. If you load the test page in your browser, you won't see anything,
regardless of (2). Our test infra adds a <pre> element to the "body"
element (which is the <frameset> element here). Such children will
never be rendered. In the future, we could come up with something
better for our test infra to do, but this isn't important anyways
for this test - we can still grab the <pre> element's innerText.
This fixes structured serialization of DataView. It was expected
to be uniform with TypedArray, which returns u32 for byte_offset().
This was covered by a number of WPT infrastructure tests, which this
commit also imports.
Previously, callers were passing the size in bytes, but the method
expected bits. This caused a crash in LibCrypto when verifying the key
size later on.
Also make the naming of local variables and parameters a little more
clear between the different AES algorithms :^)
