...before falling back to containing block. Fixes a bug when we can't
scroll innermost scrollable element, because wheel event dispatching
immediately falls back to containing block.
When trying to repro a failed CI test, it is handy to know the order in
which test-web ran its tests. We've seen in the past that the exact
order can be important to debug flakey tests.
This adds the index of the WebView running the test to verbose log
statements (which is enabled in CI).
This awkwardly sat as the internal final API for getting a StyleProperty
directly for a given PropertyID, and also the external API for getting
the StyleProperty for a PropertyID. For the latter, it lacked support
for shorthands, and for both it lacked support for custom properties.
This commit:
- Moves the code from get_property() into get_direct_property()
- Makes get_property() call get_property_internal() to support
shorthands
- Adds custom property support for get_direct_property()
This also wins us some WPT points for StylePropertyMap.
property_accepts_type() only looks at the property itself, not any
longhands it might have, so we thought that `font` didn't accept
`<custom-ident>`s, and seeing "-apple-..." makes us throw out the
declaration even though it's valid as a font name.
We'll reject these like any other unrecognized value if it's somewhere
that's not supported, so this was really just an optimization for a
rare edge case, and removing the check doesn't have any observable
effect except fixing this bug and any similar cases.
Changing property_accepts_type() to look at longhands is not
straightforward, as not all longhand values are valid in the shorthand.
The decoder was requiring GIF files to be at least 32 bytes, but the
actual minimum for a valid GIF is only 26 bytes:
- 6 bytes for the header
- 7 bytes for the Logical Screen Descriptor
- 10 bytes for the Image Descriptor
- 2 bytes for the LZW minimum code size and block terminator
- 1 byte for the GIF trailer
This change allows us to load minimal 1x1 GIFs with empty LZW data.
They are commonly used on the web as transparent placeholders with
minimal file size.
`set_source` takes a ByteString but the implementation might require a
specific encoding. Make it fallible so that we don't need to crash in
the case of invalid UTF-8 or similar.
The test includes a sequence of invalid UTF-8 bytes that crash the
browser without this change.
Instead of repeatedly removing elements off the vector, this allows for
specifying all the removed indices at once, and does not perform any
extra reallocations or unnecessary moves.
This applies size, inline-size, and style containment in some cases.
There are other WPT tests for that, but we seem to not implement enough
of containment for this to have an effect so I've not imported those.
Gets us 35 WPT subtests.
Copy parse() method from LibCore::DateTime::parse(). Augment the method
to handle parsing from GMT time. Fix incorrect handling of year in '%D'
format specifier. Remove all format specifiers related to time zones.
Copy relevant tests and add additional ones.
Whether an absbox is positioned below or to the right of its previous
sibling in an `InlineFormattingContext` is determined by the
display-outside value before blockification, so we store the
pre-blockification `display` value in `ComputedValues` to access it in
`InlineFormattingContext` and position the box accordingly.
Before this change, we always used the flex container's full available
space as the width for intrinsic (height) sizing of flex items.
This meant that flex lines with more than one flex item had their
intrinsic height determined as if they were alone on the line.
For flex row layouts, if we've already determined the flex item's main
size, we now use that as the width to get the intrinsic height.
This leads to more correct layouts, and also avoids some redundant work
since we no longer do unnecessary sizing work with the wrong width (and
can hit cache instead).
This release comes with a fix for a bug where certain unicode emoji
characters encoded in UTF-16 were mistakenly parsed as integers. This
manifested in keys of an JS object being coerced into integers, i.e.
`{ "⤵️": 42 }` would become `{ "5": 42 }`.

As it turns out, SkPath already behaves the way we need for SVG and HTML
canvas elements. Less work for us, yay! This removes a 5% item from the
profile when scrolling on https://imdb.com/
Note that there's a tiny screenshot test expectation change due to
minor antialiasing differences when we no longer do our redundant
subpath modifications.
This is required because bounding rect used in `saveLayer()` is computed
in stacking context's coordinate space.
Fixes regression introduced in ba2926f
We have a slightly odd setup here. TransformationStyleValue reifies as a
single CSSTransformComponent. It's StyleValueList that actually reifies
as a CSSTransformValue - but only if it only contains
TransformationStyleValues.
+79 WPT subtests.
This is the final CSSStyleValue class used by the per-property test
harness, so those now actually run instead of throwing an exception on
load. 🎉
+39 WPT subtests. (Plus however many from the per-property tests finally
running.)
The two failing serialization tests are also failed by Safari in exactly
the same way, so that seems more like a spec issue. (The spec is
incomplete in quite a few places.) The failing subtest for toMatrix() is
also a spec issue: is2D is handled oddly by CSSMatrixComponent and this
subtest fails because of the `matrix` getter, which is unspecified. See
https://github.com/w3c/css-houdini-drafts/issues/1155 for details.
Equivalent to the perspective() transform function.
+34 WPT subtests, and the transformvalue-normalization test now runs to
completion instead of throwing an error - though its cases still fail
until CSSTransformValue is implemented.
