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.

In particular, this property now interacts correctly when the flex
container has flex-wrap: wrap-reverse.
This caused some "regressions" in WPT tests for negative overflow in
flex containers, but the previous behavior wasn't correct either,
it just happened to give false positives on tests.
We implement these built-in accessors via a lexical environment override
on the inspected document's global scope. However, ClassicScript will
parse the script we provide as a JS program, in which any evaluated
bindings will be interpreted as global bindings. Our global binding
lookup in the bytecode interpreter does not search the lexical env for
the binding, thus scripts like "$0" fail to evaluate.
Instead, we can create an ECMAScriptFunctionObject to evaluate scripts
entered into the Inspector. These are not evaluated as JS programs, and
thus any evaluated bindings are interpreted as non-global bindings. The
lexical environment override we set will then be considered.
Similar to LadybirdBrowser/ladybird#1714.
We don't implement the linejoin values `miter-clip` and `arcs`, because
according to the SVG 2 spec:
> The values miter-clip and arcs of the stroke-linejoin property are at
> risk. There are no known browser implementations. See issue Github
> issue w3c/svgwg#592.
Nothing uses this yet. The next step is to change
SVGPathPaintable::paint() to read `graphics_element.stroke_linejoin()`
and `graphics_element.stroke_miterlimit()` when painting.
The cols and rows attributes are limited to only positive numbers with
fallback. The cols IDL attribute's default value is 20. The rows IDL
attribute's default value is 2.
The default value was returned only for the negative number. I added an
additional check for the case when the attribute is 0 to match the
specification.
Not only does this match the spec, but otherwise when the UI process
sends us the initial visibility update, we would ignore the message as
we believed we were already visible (thus the update would not reach the
document).
It's currently possible for window size/position updates to hang, as the
underlying IPCs are synchronous. This updates the WebDriver endpoint to
be async, to unblock the WebContent process while the update is ongoing.
The UI process is now responsible for informing WebContent when the
update is complete.
We can currently crash on WebDriver session shutdown when we receive a
Delete Session command. This destroys the WebDriver client while we are
inside the client's socket's on_ready_to_read callback. This is not
allowed by AK::Function.
To avoid this, we now only read data from the socket in the callback. We
then defer handling the message to break out of the callback.
By making use of the known set of supported dictionary names in that
overload set. Note that this list is typically very small (the max that
we have currently is 1).
This is really bare bone as we only support the `xyz-d50` color space
for the moment.
It makes us pass the following WPT tests:
- css/css-color/predefined-016.html
- css/css-color/xyz-d50-001.html
- css/css-color/xyz-d50-002.html
All its overrides return constants, and without virtual dispatch the
`qualified_layer_name` and `absolutized_selectors` functions can benefit
from slightly better optimizations.
`CSSRule`s aren't allocated that often, so the memory impact is minimal.
We were transforming coordinates for SVG gradients in a pretty
convoluted way: an inverse, unscaled transformation matrix was set up in
order to work around some (old?) technical limitations.
Rework this so the coordinate transformation no longer needs to be
inversed. This fixes gradients with "userSpaceOnUse" for its
gradientUnits attribute, which might cause coordinates to lie outside of
the bounding box of the gradient.
Two tests have updated reference screenshots with minor pixel updates;
this is probably the result of floating point precision improvements by
not inversing the matrix.
One test (svg-text-effects) has a bigger change: the gradient stops seem
to have moved along the text. This does seem to match other browsers
slightly better, so I'm moving forward with this ref update.
