Several /webidl/ecmascript-binding/window-named-properties-object.html
subtests, including the “[[GetOwnProperty]]” and “[[HasProperty]]”
subtests, expect iframe.contentWindow.Window.prototype[0] to return an
element with id “0”.
This commit makes the getOwnPropertyDescriptor trap accept property
keys that are integer indices, by converting them to a DOMString just
like we would for a property key that is a JSString.
Calling throw_type_error in the [[DefineOwnProperty]] trap (and
returning false) makes the internal method throw a TypeError, which
means both Object#defineProperty and Reflect#defineProperty will throw
a TypeError, but we actually want the latter to return false.
This commit makes the trap set ObjectOpResult to a TypeError (and
return true), making the internal method return false per the spec [1]
and in turn allowing Reflect#defineProperty to return false.

Update WebIDL.py
Update WebIDL.py to latest version from mozilla-central.
There were two major changes:
- [Rename legacy extended attributes in webidls](55dac83d9a) [bug 1631581](https://bugzilla.mozilla.org/show_bug.cgi?id=1631581)
- [removal of ReadableStream from WebIDL](https://phabricator.services.mozilla.com/D143074), which was solved with porting reverted removal patch (2801cc82b0)
WebIDL.Parser now has `use_builtin_readable_streams` field by default set to `true` (to use SM readable stream implementation), which could help with #29088.

script: fix BorrowError in (new Blob).slice(0,0).text()
When getting the text of a sliced Blob, we call GlobalScope.get_blob_url_id, which borrows the blob_state field mutably and calls the get_blob_size method (aka [Blob#size](https://w3c.github.io/FileAPI/#dfn-size)), which tries to borrow the same field immutably, causing a panic.
This patch inlines the relevant parts of get_blob_size into get_blob_url_id, so we can reuse the mutable borrow.

Add a "shmem" feature to selectors to avoid publishing that dependency
<!-- Please describe your changes on the following line: -->
Hopefully as a way to help #29105, this PR adds a `shmem` feature to the selectors crate. This is so that the crate can be released with that feature off by default, as the `ToShmem` derives are only of interest to Servo, I think.
All the places where servo's source code includes the selectors crate are made to turn on this feature.

Hey @jdm ,
is this issue still free? I would like to start contributing to servo.
This patch is straight from PR 28302, I thought it would be good to start with a small part, I hope that's ok.

Fixes the test case `/_mozilla/css/css-transition-cancel-event
.html`, which was failing under a specific circumstance.
The observed sequence of events during the failing test run looks like
this:
1. Transitions start in `div1` and `div2`.
2. `div1` generates a `transitionend` event.
3. The `transitionend` event handler removes `div2` from DOM, cancelling
its ongoing transition.
4. `div2` is supposed to generate a `transitioncancel` event in a timely
manner, which it does not. The test fails as a result.
What is going on here? Here's a possible explaination:
1. During one invocation of `ScriptThread::handle_msgs`...
2. In step 2, `ScriptThread::update_animations_send_events` -> `Document
::update_for_new_timeline_value` detects the completion of the
transition, and in response, pends the `transitionend` event.
3. In step 3, `ScriptThread::update_animations_send_events` ->
`Animations::send_pending_events` calls the `transitionend` handler.
4. The `transitionend` event handler removes `div2`, thereby cancelling
its ongoing transition and triggering a reflow.
5. Reflow takes place. During this, `Animations::do_post_reflow_update`
-> `Animations::handle_canceled_animations` pends the
`transitioncancel` event (precursor to step 4).
6. Having discovering that there was no running animation, `Animations::
do_post_reflow_update` calls `self.update_running_animation_presence
(_, false)`, which sends `AnimationState::NoAnimationsPresent`.
7. The invocation of `ScriptThread::handle_msgs` ends, and another
starts. It blocks waiting for events.
8. Meanwhile, the compositor receives `AnimationState::
NoAnimationsPresent` and stops further generation of animation ticks.
9. With no events to wake it up, the script thread is stuck waiting
despite having the pending `transitioncancel` event (step 4).
The HTML specification [says][1] that "an event loop must continually
run [...] as long as it exists" and does not say it can block if there
is nothing to do. Blocking is merely optimization in a user agent
implementation. Pending animation-related events must be processed every
time a "rendering opportunity" arises unless the user agent has a reason
to believe that it "would have no visible effect".
Skipping the processing of animation-related events would have visible
effect if such events are indeed present. The correct implementation in
Servo, therefore, would be to request more animation ticks so that such
events are processed in a subsequent tick.
[1]: https://html.spec.whatwg.org/multipage/#event-loop-processing-model
This commit reverses the order of the `send_pending_events` and
`update_animation_timeline` calls in `ScriptThread::update_animations_
send_events` so that animation-related events pended by the latter are
processed by the former.
The new calling order is more compliant with the "update animations and
send events" algorithm steps from [the Web Animations specification][1].
The old implementation was prone to blocking for an indefinite period
while holding pending events. Due to complex interaction with other
events and timing behavior, I was only able to reproduce the problem
under the following conditions:
- *The `maybe_observe_paint_time` call in `LayoutThread::compute_abs_
pos_and_build_display_list` is removed from the code*. While
performance events may seem irrelevant to the issue, they would
bombard the script thread with events. *Any* extra messages received
would unblock the event loop and prevent the manifestation of the
issue. (But, of course, we aren't supposed to count on that to avoid
the issue.)
- Servo is running in a headless mode, which somehow makes it less
likely for the script thread to receive a `TickAllAnimations` event
after sending `AnimationState::NoAnimationsPresent`.
With the above conditions met and the stars aligned, you can reproduce
the problem by running the WPT test `/css/css-transitions/events-001.
html`.

- Also updates raqote to latest with an upgrade of font-kit to 0.11
applied on as a patch
- Update lyon_geom to the latest version
Major change:
- All matrices are now stored in row major order. This means that
parameters to rotation functions no longer should be negated.
- `post_...()` functions are now named `then()`. `pre_transform()` is removed,
so `then()` is used and the order of operations changed.
Replace use of the deprecated RUST_SYMBOL_TO_JSID by SymbolId

A simple replacement of a deprecated function, according to changes in https://github.com/servo/mozjs/pull/315
That removes the only build warning I saw when doing a clobber.

Allow displaying content with "application/json" mime type
For me this allows the WPT test
performance-timeline/tentative/include-frames-one-remote-child.sub.html
to match expected results. The wptserver is sending a 404 JSON response
because the URL that the test requests is not found.

When turning DOM exceptions into `ErrorInfo` always try to stringify
the JavaScript value, even if it's an object that isn't a `DOMException`
or native exception. This means that exceptions that extend the `Error`
prototype are now stringified. The result is that test output for WPT
global assertion failures is more useful. For instance for the test
include-frames-from-child-same-origin-grandchild.sub.html:
Before:
```
uncaught exception: unknown (can't convert to string)
```
After:
```
uncaught exception: Error: assert_equals: expected 4 but got 3
```
Fix intermittency when loading poster images
Wait until a poster image is cached to in order to unblock document load. If not, the document may continue loading before the image is ready to use, leading to intermittency in test output. Now load is unblocked when getting the ImageResponse from the cache, which allows the code to properly unblock the load when the entire load fails or succeeds.
This reveals several false passes in the `object-view-box` test suite which were very flaky.
