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!
compute_inset() was incorrectly retrieving the containing block size
because containing_block() is unaware of grid areas that form a
containing block for grid items but do not exist in the layout tree.
With this change, we explicitly pass the containing block into
compute_inset(), allowing it to correctly provide the containing block
sizes for grid items.
If available space is definite it should always match the size of the
containing block. Therefore, there is no need to do containing block
node lookup.
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 allows us to simulate HTTP responses from Browser JS tests.
Instead of using hacks like data URLs to "load" external data,
we can now generate an actual HTTP response that contains
arbitrary headers, body, and has a defined response delay.
Gap values are now represented by Variant<LengthPercentage, NormalGap>.
NormalGap is just an empty struct to represent the `normal` keyword.
This fixes a long-standing issue where we were incorrectly storing gaps
as CSS::Size, which led to us allowing a bunch of invalid gap values.
This also adds support for `xyz` as it defaults to `xyz-d65`. We now
pass the following WPT tests:
- css/css-color/xyz-001.html
- css/css-color/xyz-002.html
- css/css-color/xyz-004.html
- css/css-color/xyz-d65-001.html
- css/css-color/xyz-d65-002.html
- css/css-color/xyz-d65-004.html
If a & simple selector is on a style rule with no parent style rule,
then it behaves like :scope - but notably, :scope provides 1
specificity in the class category, but & is supposed to provide 0.
To solve this, we stop replacing it directly, and just handle the & like
any other simple selector. We know that if the selector engine ever
sees one, it's equivalent to :scope, because the nested ones will have
been replaced with :is() before that point.
This gets us one more subtest pass. :^)
When we first parse a nested CSSStyleRule's selectors, we treat them as
relative selectors and then patch them up with an `&` as needed.
However, we weren't doing this when assigning the `cssText` attribute.
So, let's do that!
This gives us a couple of subtest passes. :^)
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
If a rule gets its caches cleared because it's moved in the OM, then its
child rules' caches are likely invalid and need clearing too.
Assuming that caches only point "upwards", this will correctly clear
them all. For the time being that will be true.
