The HTML specification does not explicitly require
a specific return type for parseFromString(),
but according to Web Platform TestsDOMParser-parseFromString.html,
the expected return value for
XML MIME types is a Document—not an XMLDocument.
A "namespace prefix map", see:
https://w3c.github.io/DOM-Parsing/#the-namespace-prefix-map
Is meant to also hold null namespaces:
> where namespaceURI values are the map's unique keys
> (which can include the null value representing no namespace)
Which we previously neglected. This resulted in a crash for
the updated WPT test.
Documents created via DOMParser.parseFromString()
are parsed synchronously and do not participate in the
browsing context's loading pipeline.
This patch ensures that if the document has no browsing context
(i.e. was parsed via DOMParser),
its readiness is set to "complete" synchronously.
Fixes WPT:
domparsing/xmldomparser.html
This allows us to disable test output, which performs expensive assert
tracking. This was making our imported tests run significantly slower
than tests run via `WPT.sh`.
Formatting the output ourselves also allows us to remove unnecessary
information from the test output.
This commit also rebaselines all existing imported WPT tests to follow
the new format.
While the code that did this referred to the HTML spec, other browsers
appear not to have this behavior when parsing XML, and it breaks a WPT
subtest.
This change does not appear to break any tests, and fixes 1 WPT subtest.
Previously any existing ElementInlineCSSStyleDeclaration would get
overwritten by e.setAttribute("style", ...), while it should be updated
instead.
This fixes 2 WPT subtests.
When serializing an sRGB color value that originated from a named color,
it should return the color name converted to ASCII lowercase. This
requires storing the color name (if it has one).
This change also requires explicitly removing the color names when
computing style, because computed color values do not retain their name.
It also requires removing a caching optimization in create_from_color(),
because adding the name means that the cached value might be wrong.
This fixes some WPT subtests, and also required updating some of our own
tests.
