The streams AO that we were calling to close the stream would assert
if it was not in a readable state. This version of close is exported
publicly in the streams specification, and properly handles this
situation.
Fixes a crash in the imported test, and happens to fix some others!
This exposed a few bugs which caused the following tests to behave
incorrectly:
- `tab-size-text-wrap.html`: This previously relied on a bug where we
incorrectly treated `white-space: pre` as allowing text wrapping. The
fix here is to implement the text-wrap CSS shorthand property.
- `execCommand-preserveWhitespace.html`: We don't correctly serialize
shorthand properties. This is covered by an existing FIXME in
`CSSStyleProperties::serialized()`
- `white-space-shorthand.html`: The last 5 subtests here fail as we
don't correctly handle shorthand properties in
`CSSStyleProperties::remove_property()`. This is covered by an
existing FIXME in said function.
When an element's ID is removed we only want to remove it from
`m_potentially_named_elements` if it is not also considered a
potentially named element due to it's name content attribute.
This begins implementation on form-associated custom elements.
This fixes a few WPT tests which I'm importing.

While width and height are presentational hints on canvas, they actually
map to the CSS aspect-ratio attribute, not to CSS width and height.
For this reason, we actually need to manually mark for relayout here.
Also import a WPT test that was flaky before this change.
This implements the previously stubbed out `report_validity` method.
The specification is not very clear on how to exactly report the
validity. For now, we bring the first visible invalid control into
view and focus it. In the future, however, it would make sense to
support more complex scenarios and be more aligned with the other
implementations.
Importing these tests now because they are for input-element types that
have requirements related to the constraint-validation API — which we’ve
been implementing recently.
This commit only imports tests, without any changes to our code.
The property-reflection.html test was partially split into a second file
recently, property-reflection-imperative-setup.html. Let's re-import to
ensure we have the latest. See:
https://github.com/web-platform-tests/wpt/commit/2518df1
Math functions like abs(), clamp(), round(), etc, can be used by
themselves in property values, without wrapping them in calc().
Before this change, we were neglecting to run calc simplification on the
generated calculation node trees. By doing that manually after parsing a
standalone math function, we score at least a couple hundred WPT points.
