Better support for CSS shorthands when setting the style attribute. This
improves some tests in WPT /css/css-align/default-alignment/*shorthand.
When setting the style attribute in JS via element.style = '..' or the
setAttribute method, shorthand properties were not expanded to longhand
properties.
Previously, attempting to parse a floating point number with an integer
part larger than `(2 ^ 31) - 1` would cause the browser to crash. We now
avoid this by converting the integer part of the number to a `double`
rather than an `i32`.
The spec says that "isTrusted is a convenience that indicates whether
an event is dispatched by the user agent (as opposed to using
dispatchEvent())"
But when dispatching a pageshow event the flag was incorrectly set
to false.

We were hard-coding "about:blank" as the document URL for parsed HTML
documents, which was definitely not correct.
This fixes a bunch of WPT tests under /domparsing/ :^)
This resolves all WPT timeouts in html/canvas/element/manual/imagebitmap
We can now run an additional 6 tests and 126 subtests :)
This also adds regression tests for this behavior.
DedicatedWorkerGlobalScope is an object with a Global extended
attribute, but does not define any named property getters. This needs to
be handled by setting the prototype chain to:
DedicatedWorkerGlobalScope
^ DedicatedWorkerGlobalScopePrototype
^ WorkerGlobalScopePrototype
(This is different from something like Window, where there is an
intermediate WindowProperties object for named properties.)
Previously, we treated the GlobalMixin object as if it was a simple
prototype object, accidentally setting DedicatedWorkerGlobalScope's
prototype to WorkerGlobalScopePrototype. This caused the expression
self instanceof DedicatedWorkerGlobalScope
to return false inside workers.
This makes us pass many more of the "/xhr/idlharness.any.worker" WPT
tests than before, rather than failing early.
Previously, if there was an unhandled exception in an async test, it
might fail to call done() and timeout. Now we have a default "error"
handler to catch unhandled exceptions and fail the test. A few tests
want to actually test the behavior of window.onerror, so they need an
escape hatch.
Fixes at least one WPT test that was previously timing out:
- html/semantics/document-metadata/the-base-element/base_target_does_not_affect_iframe_src_navigation.html
For example, in the following abbreviated test HTML:
<span>some text</span>
<script>println("whf")</script>
We would have to craft the expectation file to include the "some text"
segment, usually with some leading whitespace. This is a bit annoying,
and makes it difficult to manually craft expectation files.
So instead of comparing the expectation against the entire DOM inner
text, we now send the inner text of just the <pre> element containing
the test output when we invoke `internals.signalTextTestIsDone`.
The events tested here are decidedly async. We also can't really write
sync tests of the form "test(async () => {})". Nothing will await the
async callback.
We now use the "report an exception" AO when a script has an execution
error. This has mostly replaced the older "report the exception" AO in
various specifications. Using this newer AO ensures that
`window.onerror` is invoked when a script has an execution error.
This fixes an issue where document.write() with only text input would
leave all the character data as unflushed text in the parser.
This fixes many of the WPT tests for document.write().
This change ensures that the value sanitization algorithm is run and
the text cursor is set to the correct position when the type attribute
of an input is changed.
In particular, there was an assertion failure due to the temporary
parser document's "about base URL" being empty when trying to "parse a
URL" during parsing.
We fix this by copying the context element's document's about base URL
to the temporary parsing document while parsing a fragment.
This fixes a crash when loading search results on https://amazon.com/
The IDL constructor has to take separate steps than a DataTransfer that
is internally constructed. Notably, an IDL-created object has its own
drag data store, and that store is placed in a read-write mode.
