We now follow the rules from the spec more closely, along with an
unspecified quirk for when the offsetParent is a non-positioned body
element. (Spec bug linked in a comment.)
This fixes a whole bunch of css-flexbox tests on WPT, which already had
correct layout, but the reported metrics from JS API were wrong.
We now ensure that `Node::is_character_data()` returns true for all
nodes of type character data.
Previously, calling `Node::length()` on `CDataSection` or
`ProcessingInstruction` nodes would return an incorrect value.
We were mistakenly executing the current node's script instead of the
document's pending parsing-blocking script.
This caused ~1000 WPT tests to time out, since we never ended up firing
a load event for XHTML pages that load multiple external scripts.
Before this change, "background-clip: text" was implemented by saving a
Vector<Gfx::Path> of all glyphs needed to paint a mask for the
background. The issue with this approach was that once glyphs were
extracted into vector paths, the glyph rasterization cache could no
longer be utilized.
With this change, all text required for mask painting is saved in a
nested display list and rasterized as a regular text.
This change is a preparation for the upcoming changes where display
list will be nested and the same display could be owned by multiple
display list items.
With this change display list player will be able to recurse into
executing another display list, without having to construct new display
list player. It is going to be useful in the upcoming changes to paint
a mask from a display list owned by a command.
Previously, when creating a HTML element with
`document.createElementNS()` we would convert the given local name to
lowercase before deciding which element type to return. We now no
longer perform this lower case conversion, so if an uppercase local
name is provided, an element of type `HTMLUnknownElement` will be
returned. This aligns our implementation with the specification.
Instead of multiple loops and multiple vectors, parse Wasm expressions
in a simple loop. This gets us from ~450ms to instantiate spidermonkey
to ~280ms.
`swizzle` had the wrong operands, and the vector masking boolean logic
was incorrect in the internal `shuffle_or_0` implementation. `shuffle`
was previously implemented as a dynamic swizzle, when it uses an
immediate operand for lane indices in the spec.
CommandResult was needed by LibGfx display list player that could have
failed to allocate a temporary bitmap for painting a stacking context
with CSS transforms. This is no longer an issue with Skia painter, so
we can delete CommandResult::SkipStackingContext handling path.
This is called by https://athenacrisis.com/ and passed through to
AudioNode.connect, which expects an AudioNode.
Implement this function enough so that we return an AudioNode so that
AudioNode.connect does not throw a TypeError.
This is an AudioNode representing the final audio destination and is
what the user will ultimately hear.
This node is used as one of the connecting nodes in athenacrisis.com
Add a placeholder for the interface without anything backing it for now.
With this change, instead of recording a display list item for each
instance of a repeated background, a new DrawRepeatedImmutableBitmap
type is used. This allows the painter to use optimized repeated image
painting and, when the GPU backend is used, avoid re-uploading the image
texture for each repetition.
Some screenshot tests are affected, but there are no visible
regressions.
https://null.com/games/chainstaff works a lof faster with this change.
The :host family of pseudo class selectors select the shadow host
element when matching against a rule from within the element's shadow
tree.
This is a bit convoluted due to the fact that the document-level
StyleComputer keeps track of *all* style rules, and not just the
document-level ones.
In the future, we should refactor style storage so that shadow roots
have their own style scope, and we can simplify a lot of this.
This fixes an issue where :host(foo) would parse as if "foo" was the
on the right side of a descendant combinator.
Not testable yet, but will be in the next commit.
We don't want to set the intrinsic Console object's client to non-top-
level clients, created for e.g. SVG elements or subframes. We also want
to make sure the Console client is updated if the top-level document has
changed.
Checking that the string parsed for the `font` property is not enough,
the spec also wants to rule out CSS-wide keywords like `inherit`. The
simplest way to do so is to check if it's a ShorthandStyleValue, which
also rules out use of `var()`; this matches other browsers' behaviour.
The newly-added test would previously crash, and now doesn't. :^)
