This update makes service workers properly show up in DevTools and
behave more like dedicated workers.
- Added an is_service_worker field to DevtoolsPageInfo so the devtools
server can tell service workers apart from dedicated workers
- Triggered a NewGlobal message when a service worker is created in
serviceworker_manager.rs, similar to what already happens for dedicated
workers
- Routed service workers to root.service_workers so they appear under
"Service Workers" in about:debugging instead of "Other Workers"
- Implemented listServiceWorkerRegistrations with the expected response
format (activeWorker, installingWorker, waitingWorker, evaluatingWorker)
to match Firefox’s LegacyServiceWorkersWatcher
- Added support for getPushSubscription in WorkerActor, currently
returning subscription: null
Enabled the service_worker target type in the watcher’s SessionContext
and handled watchTargets("service_worker")
Testing
Start Servo with:
`RUST_LOG="error,devtools=debug" ./mach run --
--pref=dom_serviceworker_enabled --devtools=6080
"https://mdn.github.io/dom-examples/service-worker/simple-service-worker/"
`
In Firefox, go to about:debugging and connect to localhost:6080
Confirm the service worker shows up under "Service Workers"

There were two issues here:
1. We weren't firing the `load` event when we would show an error page
because of a CSP failure. This is to avoid web pages knowing wheter a
page has failed because of CSP.
2. We were reporting the violations in the wrong global. We shouldn't
fire these in the global of the child, but instead in the parent.

Currently, the `web_font_finished_loading_callback` sends a
`ScriptThreadMessage::WebFontLoaded` message regardless of whether web
font loading succeeds or not, which leads to dirtying all nodes in
`script_thread.rs`. This creates unnecessary reflow. This PR removes the
boolean field from the `WebFontLoaded` message and only sends the
message when the web font loading is successful.

We now check for this header and corresponding logic. The WPT tests
mostly pass, but rely on the `contentDocument` of the iframe to be
`null`. This is not something we did before, which means that iframes
were able to access the contents of error pages.
Instead, we now mark the document as internal with an opaque origin
according to the spec [1]. We shouldn't do this post-fact, but is
required since we first need to construct the document and enter its
realm, before we determine that it is an invalid document.

in #42336, we added a
[Servo](https://doc.servo.org/servo/struct.Servo.html)-global API for
controlling whether accessibility is active. the idea was that when the
embedder activates accessibility, all webviews and documents activate
accessibility and start sending AccessKit tree updates, and vice versa
when they deactivate.
we found a problem with this approach in #42338. global activation of
accessibility makes it too easy to accidentally cause a panic in
AccessKit, and harder than it needs to be for embedders to learn that
they are responsible for grafting each webview’s subtree into their main
AccessKit tree as soon as accessibility is activated. this is due to an
invariant of the AccessKit subtree API: if a subtree starts sending
updates before the graft node is created, the program panics.
this patch reworks accessibility activation to make it per-webview. by
requiring embedders to explicitly activate accessibility for a webview,
we can communicate the AccessKit invariant via our API docs.
Testing: this patch includes an initial accessibility test in libservo

The console actor sends `Eval` via debugger.js, not `EvaluateJS`.
Workers only handled `EvaluateJS` which was never sent. We would want to
use `Eval` for workers as well. The worker evaluation was already
non-functional.
One more motivation behind not keeping this legacy path is because it
requires passing `None` for all new fields added to
`EvaluateJSReplyValue`, that is extra burden.

This is a hot path:
- there is a lot of processing in `handle_pending_input_events`: JS
realm entry, temporary variable creation, value assignment etc.
- we acquire a RAII guard before calling the function.
If the event queue is empty, this would result in unnecessary overhead
on the hot path.
We skip all above work in this case.
Testing: This is an optimization that should not change visible

Add support for navigation requests ("navigateTo", "goBack", and
"goForward") over the Remote Debugging Protocol. These may be sent by a
UI client in response to user input (for example the address bar in the
Firefox inspector), or they can be used to automate navigation during
unit tests.
This currently only supports navigation within the URL domain at which
servoshell is initially launched, due to a bug in servo's
`BrowsingContextActor` implementation. (Unit tests covering a fix for
that issue will depend on this change.)

This changes makes it so that keyboard and click focusability are two
separate concepts in `script`. Some elements may be focusable only by
the keyboard and some only by the click events.
In addition, the `SEQUENTIALLY_FOCUSABLE` `Node` flag is removed in
favor of a
more specification-aligned approach of checking lazily if an element is
a focusable area. This allows moving the focus fixup steps to their
correct place, asynchronously during "update the rendering" and
synchronously during `unbind_from_tree`.
Testing: This causes some WPT tests to start passing and some to start
failing:
- Two subtests tests in
`tests/wpt/meta/css/css-conditional/container-queries/` because
we do not implement support for container queries. These are legitimate
failures
and they are compensated by a good subtest pass in the same file.
- A few subtests in `/html/interaction/focus/tabindex-focus-flag.html`
because now
we do not allow focusing non-rendering elements. The failures are HTML
elements with
`<svg>` which we do not rendering and `<summary>` elements of
`<details>` which
need special handling we do not implement yet.
- `html/semantics/forms/the-fieldset-element/disabled-003.html`: Some of
these tests
start to fail, but they are not spec compliant and browser properly
implementing
the asynchronous focus fixup rule also fail them.

Remove embedder defined `ScrollEvent` and merge the payload of it to the
`SetScrollStates` message which tell the `ScriptThread` to update the
scroll state.
In the past, `ScrollEvent` is defined as a embedder's `InputEvent` and
being used only to forward the external scroll node id for a node that
is considered scrolled. This make us sends an additional message to
constellation and additionally, `ScrollEvent` went through lengthy
pipelines as it was deemed as an embedder input event, albeit being a
synthetic input fired by `WebviewRenderer`.
Subsequently, we could introduce a flag to detect whether the scrolling
is still ongoing or not (like whether it is still flinging) for
`scrollend` event.

Currently, `script` and `devtools` use a node's unique id to identify it
across requests. The unique ID is part of a node's rare data field and
is really only meant for debugging. Instantiating it on a node causes
it's memory usage to go up significantly. Now, when the devtools ask for
information about a specific `Node` then they send the unique ID to
`script`, and the script thread then walks the whole DOM tree searching
for that specific ID. This happens here:
6d0b651218/components/script/devtools.rs (L142-L153)
So, in the worst case, all of the nodes in the tree now have a unique
ID. That's not great!
Also, when `script` notifies `devtools` about changes to a DOM node then
`devtools` expects a `NodeActor` to exist for that Node. The actor might
not exist if the inspector doesn't know about that node yet - that
happens when the user hasn't expanded their parent yet.
That is an oversight from https://github.com/servo/servo/pull/42601 and
causes problems now(https://github.com/servo/servo/issues/42784) because
for the longest time, `devtools` was mostly the one sending requests. Of
course, we could make `devtools` simply ignore updates for nodes that it
doesn't know about, but ideally we shouldn't send these updates in the
first place.
This change implements a lookup map on the `ScriptThread` that contains
all nodes that have been sent to the devtools inspector. The map allows
us to efficiently resolve a unique ID to a `Node` in O(1), without
creating unique IDs for the whole tree. It also allows us to only send
DOM updates for nodes that the inspector cares about.
For now, entries from the cache are not evicted unless the relevant
pipeline is closed. That reflects reality, because the inspector also
keeps using them forever.
In the future we will tell the inspector when nodes are removed from the
tree - then it can't interact with them anymore, and we can remove them
from the script-side map.
This is change is not all that complicated but it involves moving a lot
of code around, so feel free to ask for clarification when something is
unclear!
