- Remove the last remaining Servo-specific PseudoElement enum from
layout. This was made to select `::before` and `::after` (both eager
pseudo-elements), but now `traverse_pseudo_element` is called
`traverse_eager_pseudo_element` and should work on any eager pseudo
element.
- Expose a single way of getting psuedo-element variants of
ThreadSafeLayoutElement in the Layout DOM, which returns `None` when
the pseudo-element doesn't apply (not defined for eager
pseudo-elements or when trying to get `<details>` related
pseudo-elements on elements that they don't apply to).
- Ensure that NodeAndStyleInfo always refers to a node. This is done by
making sure that anonymous boxes are all associated with their
originating node.
These changes are prepatory work for implementation of the `::marker`
pseudo-element as well as ensuring that all anonymous boxes can be
cached into the box tree eventually.

The DOM event listener "removed" status should be supported to track
the following situations (with immediate effect of listener removal):
- 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
and the lowercase "event listener" concept in Servo is EventListenerEntry

In the fetch spec, the `text()` method of `Body` (an interface mixin
implemented by both `Request` and `Response`) consumes the body with
the Encoding spec "UTF-8 decode" algorithm, which skips the UTF-8 BOM
if it is present at the beginning of the body. Servo's implementation
does not do that. This patch fixes this.

When you create a `Request` object with a `FormData` body, the spec
says that the `Content-Type` header should start with
`multipart/form-data; boundary=`. However, in Servo's implementation
it started with `multipart/form-data;boundary=`, without the space.
While all reasonable servers should be able to that headers whether
the space is present or not, this brings Servo closer to the spec, and
also makes some WPT tests pass.
Note that submitting a form with `enctype="multipart/form-data"` does
produce a `Content-Type` header with the space (see
`HTMLFormElement::submit_entity_body`).

Aligns the implementation with step 8.5 of the HTML spec for parsing
a <template> element in the InHead state by setting
shadow_root.set_available_to_element_internals(true) after
assigning the shadow root to the template’s contents.
Also removes tests/wpt/meta/shadow-dom/declarative/declarative-shadow-dom-available-to-element-internals.html.ini
since the test expectations are now updated accordingly.

Introduce a test to reproduce and verify the fix for backspacing at the

newline without deleting the entire previous line’s content.

* fix(textinput): Preserve selection origin when adjusting vertical position
Fixes an issue where pressing Backspace at the beginning of a line in a
textarea incorrectly deleted the entire previous line's content. This happened
because `self.adjust_vertical(-1, select)` modified `selection_origin` and
`edit_point`, but `selection_origin` was not restored before performing the
horizontal adjustment. As a result, `self.selection_start()` and
`self.selection_end()` were inconsistent, leading to `replace_operation`
erasing the entire line.
Now, we temporarily store `selection_origin` before adjusting vertical
position and restore it afterward to ensure proper cursor and selection
behavior.

Sometimes column Flexbox needs to do an early layout pass to determine
the preferred block content size of flex items. Previously the
absolutely positioned children created during this pass were discarded,
but now they are cached to be possibly used during the final layout
phase of the flex item. Since they are not thrown away, it is necessary
that the `PositioningContext` used to collect them is compatible with
their final `PositioningContext`.
Fixes#36121.

Spec: https://drafts.csswg.org/css-sizing-3/#funcdef-width-fit-content
It's similar to the `fit-content` keyword but, instead of clamping the
stretch size between `min-content` and `max-content`, it clamps the
provided argument.
So now that we support `fit-content`, it's quite straightforward to add.
It's just not completely clear what should happen when the argument has
a cyclic percentage, so this may need some further adjustments depending
on the outcome of https://github.com/w3c/csswg-drafts/issues/11805

The HTML specification states that an input element with the `readonly`
attribute must be barred from constraint validation. Our implementation
previously included an extra check (`does_readonly_apply()`) to verify
if `readonly` applies to the input type, which is unnecessary.
This caused three test failures in:
tests/wpt/meta/html/semantics/forms/constraints/form-validation-willValidate.html.ini
- Removed `does_readonly_apply()` as it is not required for validation.
- Removed `tests/wpt/meta/html/semantics/forms/constraints/form-validation-willValidate.html.ini` since the test now passes.

Simply how `ProgressiveWebMetrics` works:
1. Keep only a single struct instead of one in layout and one script
that both implement the `ProgressiveWebMetrics` trait. Since layout
and script are the same thread these can now just be a single
`ProgressiveWebMetrics` struct stored in script.
2. Have the compositor be responsible for informing the Constellation
(which informs the ScripThread) about paint metrics. This makes
communication flow one way and removes one dependency between the
compositor and script (of two).
3. All units tests are moved into the `metrics` crate itself since there
is only one struct there now.

In #35630 I treated an indefinite `stretch` as 0px on min sizing
properties, and as `none` on max sizing properties. However, this was
only for final layout sizes, I forgot about intrinsic contributions.
Blink already modified the relevant test, I'm just reordering it a bit
since we are no longer treating `stretch` as `fit-content`, so it seems
better to test it at the end.
