To be able to abort the update, extract the functionality into a
separate method. Otherwise, we don't run the `node.rev_version` at the
end, which according to the comment is probably important.
Not all `style-src` tests pass and I don't fully understand why yet, but
I presume it has to do with some special quirks of stylesheets that
other CSP checks don't have. All `style-src-attr-elem` tests pass
though.

`ensure_rare_data` returns a RefMut that extends the borrow of
Node.rare_data. This can lead to a panic in any method that triggers a
GC while this borrow is outstanding, such as Node.childNodes.
Testing: Manual testing on the testcase from the issue. It is impossible
to create a deterministic WPT crash test that is fast enough and can be

to perform memory reporting once the reporting is complete, 2) memory
reporting for the system font service. There are various other commits
that remove `#[ignore_malloc_size_of]` attributes for data that we are
now able to measure, but they do not significantly change our
measurements when testing servo.org.

The existing code asserts that attribute nodes are never serialized.
This is wrong, because you can pass an attribute node to
`XMLSerializer::serializeToString`. Instead, the spec mandates that
these are serialized as empty strings

If a `WebView` is dropped immediately after creating it, the exit
pipeline message can arrive to the `ScriptThread` before the `Document`
is created for the pipeline. If this happens, we should still send a
message to the `Constellation` informing it that the pipeline is closed,
otherwise it will never know that this has happened properly.

This change removes the early return in `MessagePort::Close` that
occurred when the message port was detached. The

Rather than sharing the full image cache in a script_thread, the image
cache is now unique per document. This ensures that CSP factors no
longer affect whether the image is retrieved from the cache incorrectly.
To do so, the thread_pool is shared across all caches, but the store is
fresh. Except for the place_holder{image,url}, which are cloned. That's
because the `rippy_data` is only available in the constellation and no
longer accessible at the point that we need to create the document in
the script_thread.
Contrary to the description in #36505, the script_thread still has an
image_cache for this reason: so it has access to the store and
thread_pool to clone it.
With these changes, the two CSP tests no longer flake. Confirmed with
running the following commmand:
```
./mach test-wpt tests/wpt/tests/content-security-policy/generic/ --rerun=10

As a follow-up to the recent introduction of `script.src`
as trusted sink, this PR refactors machinery to also
support `TrustedScript`. In doing so, all trusted sinks
in `HTMLScriptElement` are now covered.
Instead of calling the callbacks in `policy.createX`,
we now have a `TrustedType` enum that specifies which callback
to invoke. Unfortunately we still have the `USVString` vs
`DOMString` problem, which is why we need to `.map` twice
to retrieve the backing `String` and avoid two different
types.
Additionally, I saw that `script.text` should have called
the "String replace all" algorithm rather than setting the
child contents. So that's also now fixed.

Previously, spans were partially clamped during layout, but this means
that accessing and setting these properties via script wouldn't behave
according to the HTML specification. In addition, the value wasn't

This macro does not hide any complex or unsafe implementation details,
and, it's only used in two files (node.rs and element.rs). This patch
removes the macro, and move the implementation in place.
Moreover, the Element::rare_data_mut function in element.rs is called by
other functions, so the #[allow(dead_code)] annotation is removed. The
Node::rare_data_mut function in node.rs is not called anywhere, so it is
removed.
Testing: No test is needed for this cleaning up.
