This was previously still valid since the `Optional<String>` move
constructor copied its input, but since the move is now destructive,
the code no longer works.
`Optional` and `Variant` both use essentially the same pattern of only
declaring a copy constructor/move constructor/destructor and copy/move
assignment operator if all of their template parameters have one.
Let's move these into a macro to avoid code duplication and to give a
name to the thing we are trying to accomplish.
Stealing the callbacks from the AnimationFrameCallbackDriver made them
no longer safe from GC. Continue to store them on the class until we
have finished their execution.
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.
The DOM spec gets overridden by both the SVG2 and MathML core specs in
that unknown elements should not inherit DOM::Element, but
SVG::SVGElement and MathML::MathMLElement respectively.
This is a mixin in the IDL, so let's treat it as a mixin in our code and
let both SVGElement and MathMLElement reuse the implementations that we
wrote for HTMLElement.
This change helps to ensure issue authors include the details needed to
reproduce problems — including repro steps, expected behavior, a reduced
test case, and logs/backtrace.
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`.
This change makes the Meta/import-wpt-test.py script handle URLs such as
https://wpt.live//WebCryptoAPI/generateKey/../util/helpers.js and paths
containing, e.g., wpt-import/WebCryptoAPI/generateKey/../util/helpers.js
(that is, URLs and paths with “..” parent-directory references in them).
Otherwise, without this change, when the import-wpt-test.py script tries
a URL like https://wpt.live//WebCryptoAPI/generateKey/../util/helpers.js
which contains a “..” parent-directory reference, the script fails with
a “urllib.error.HTTPError: HTTP Error 404: Not Found” error message.
