Root nodes for the duration of their CSS transitions
This ensures that we can pass a node address as part of the asynchronous
transition end notification, making it safe to fire the corresponding
DOM event on the node from the script thread. Without explicitly rooting
this node when the transition starts, we risk the node being GCed before
the transition is complete.

Otherwise we can have a situation like this:
<style>
.notmatching > #foo {}
</style>
<span id="foo"></span>
<span></span>
and the style sharing cache lookup for the second <span> would try to revalidate
against the cached value for the first <span>, but end up failing asserts about
the two elements matching lists of revalidation selectors that have the same
length.
Make cross-origin canvas drawing tests use a same-origin redirect.
These tests either pass or maintain existing known failures in Firefox and Chrome, and expose the problem in our current implementation that #15887 is addressing.

This avoids the need for multiple layout RPC operations immediately
following return of control to script. This means that layout and
script can continue to operate in parallel at this point, rather
than one potentially waiting on the shared mutex to be unlocked.
This ensures that we can pass a node address as part of the asynchronous
transition end notification, making it safe to fire the corresponding
DOM event on the node from the script thread. Without explicitly rooting
this node when the transition starts, we risk the node being GCed before
the transition is complete.
Fix dynamic updates when :dir matching changes in stylo.

In a similar way to Position, now specified and computed gradients share
a common Gradient type defined in style::values::generics::image.
This allows us to reuse most code for many style traits like ToCss,
HasViewportPercentage and ToComputedValue.
The test changes are the fallout of the disappearance of AngleOrCorner::None,
which align our code to the spec for serialisation, where components that can
be omitted should be omitted.
This patch implements the following changes:
- Only check for the toplevel/sublevel part of the mime type when
deciding if it's a js or css resource, ignoring the mime parameters.
- Fix the wpt tests that did not escape url parameters properly and
also used an invalid syntax for the mime parameter.
- Update the wpt manifest.
Update mozjs_sys

style: Set root font-size right after cascading font-size
This way rem in the root element works as expected.
This fixes layout/reftests/css-valuesandunits/unit-rem-root-width.html in Gecko.

stylo: -moz-image-region shouldn't parse unitless lengths in quirks mode
For clip property, `ClipRectOrAuto` was parsing its lengths without units in quirks mode. But `-moz-image-region` property should reject unitless lengths according to gecko. This fixes a stylo test failure.
