The label that is displayed inside a `<select>` element is that of the
selected option, or it's text contents if the option does not have a
label. Therefore, we need to update the `<select>` shadow tree when the
contents of the selected option change.

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
floored in layout, so could lead to panics. This change improves
clamping and moves it to script.
Testing: This change includes a new WPT test.
Fixes#36699.

Implement
[disentangle](https://html.spec.whatwg.org/multipage/#disentangle)
Remove bespoke gc logic which now becomes unnecessary.
Adds a wpt test that hits the "disentangle while in transfer" logic.
Updates streams code, fixing an error where disentanglement is
conditional on an error.
Test coverage: there are existing tests in
`/webmessaging/message-channels/close-event/explicitly-closed.tentative.window.js`
for the no transfer case, and the simple completed transfer case, and
this PR adds a test for the more complicated transfer in progress case.

This PR updates the validity state revalidation behavior for radio input
elements, ensuring consistent logic regardless of tree connectivity.
---
**What’s changed:**
- we now always update the validity state.
- Handled more edge cases for disconnected trees, shadow roots, and
cross-tree movement.
- Ensured that radio group updates still trigger when a parent is moved
into a different root.
- Updated test expectations in
`radio-disconnected-group-owner.html.ini`.
---
**Why this matters:**
The updated logic aligns better with the [HTML
specification](https://html.spec.whatwg.org/multipage/input.html#radio-button-group),
especially regarding radio group behavior in disconnected trees or
shadow DOM.
These changes improve validity propagation in scenarios like:
- Appending inputs into a disconnected form
- Shadow roots acting as radio group containers
- Cross-tree movement of radio buttons
---
**Tests:**
- Modified `radio-disconnected-group-owner.html.ini`
- Removed a test that now passes
- Added a failing test expectation caused by a spec bug: the fragment
parsing algorithm uses the connected tree for HTML set via `innerHTML`,
affecting radio group computation

Each canvas context returns snapshot instead of just raw bytes. This
allows as to hold off conversions (BGRA <-> RGBA, (un)premultiply) to
when/if they are actually needed. For example when loading snapshot into
webgl we can load both RGBA and BGRA so no conversion is really needed.
Currently whole thing is designed to be able to be extend on
https://github.com/servo/ipc-channel/pull/356, to make less copies.
Hence some commented out code.

This PR resolves [#36592](https://github.com/servo/servo/issues/36592)
by updating the `RequestBuilder` used in `script_module.rs` to include:
- `insecure_requests_policy`
- `has_trustworthy_ancestor_origin`
- `policy_container`
These fields are critical for enforcing proper fetch behavior under
modern web security models, and were previously omitted from module
script requests.
This change ensures that scripts loaded via `<script type="module">` or
dynamic `import()` correctly reflect the calling document’s security
environment.

The JS engine uses types like `Handle<Maybe<PropertyDescriptor>>` in
various places and our automated bindings are not able to handle the
Maybe type. We have hand-written bindings that use outparams to indicate
a PropertyDescriptor value is actually the Nothing type, but that data
was getting lost when we passed the property descriptor to
SetPropertyIgnoringNamedGetter, which assumed that the property
descriptor was always valid.

It also updates the FetchResponseListener to process CSP violations to
ensure that iframe elements (amongst others) properly generate the CSP
events. These iframe elements are used in the Trusted Types tests
themselves and weren't propagating the violations before.
However, the tests themselves are still not passing since they also use
Websockets, which currently aren't using the fetch machinery itself.

This PR addresses a crash in text input element due to a hack to prevent
text input being trimmed.
The updated behavior will only add `zero width space` unicode character
to the node if there's no text content instead of adding it constantly.
Also by adding the same `zero width space` unicode character to text
area when there's no text content within will allow text area element to
properly display caret.

Among other things this adds a new `EmbedderMsg::ShowSelectElementMenu`
to tell the embedder to display a select popup at the given location.
This is a draft because some small style adjustments need to be made:
* the select element should always have the width of the largest option
* the border should be part of the shadow tree
Apart from that, it's mostly ready for review.

- Removing a later event listener while an earlier listener
for the same event is running
- Nested usage (recursively dispatch another event) of "once" listeners
https://dom.spec.whatwg.org/#event-listener-removed
During event dispatching requires to clone event listeners list
on "invoke" step https://dom.spec.whatwg.org/#concept-event-listener-invoke
