We don't need AI/ML features in the tests, so this should reduce CPU
usage by not having the inference process running. Moreover, it prevents
the following lines from being logged in the test output:
```
JavaScript error: resource://gre/actors/MLEngineParent.sys.mjs, line 509: Error: Unable to get the ML engine from Remote Settings.
JavaScript error: resource://gre/actors/MLEngineParent.sys.mjs, line 1279: TypeError: can't access property "postMessage", this[#port] is null
```
Implement a delay for Chrome protocol calls in the integration tests, and skip the "must check that an existing highlight is ignored on hovering" integration test on Windows
This is a temporary measure to reduce noise until #20136 is fixed. Note
that this shouldn't be an issue in terms of coverage because we still
run the test on Linux.
In Chrome protocol calls are faster than in Firefox and thus trigger in
quicker succession. This can cause intermittent failures because new
protocol calls can run before events triggered by the previous protocol
calls had a chance to be processed (essentially causing events to get
lost).
This commit fixes the issue by configuring Chrome with a protocol call
delay value that gives it a more similar execution speed as Firefox
(which also gives us more consistency between the two browser runs).
Note that this doesn't negatively impact the overall runtime of the
integration tests because Puppeteer already waits for a test to complete
in both browsers before continuing to the next one and Chrome
consistently was, and with this patch still slightly is, faster in
completing the tests.
It should fix the error:
```
JavaScript error: http://127.0.0.1:43303/build/generic/build/pdf.mjs, line 1445:
TypeError: EventTarget.addEventListener: 'signal' member of AddEventListenerOptions is not an object.
```
we've when running integration tests on the Linux bot.
In #20016, the `canvasContext` property of `RenderParameters` was deprecated in favor of the new `canvas` property.
The JSDoc was updated to include the new parameter along with the old one.
I think the old one should be enclosed in `[]` to mark it as optional (and to allow usage from TypeScript with just the `canvas` parameter provided).
I also reordered the properties so that all required properties come first, follow by optional ones.
The fixed -400px horizontal offset used by
scrollIntoView led to horizontal scroll only moving
part-way right on narrow screens. The highlights near
the right-edge remained party or completely off
screen.
This centres the highlighted match on any viewport width while
clamping the left margin to 20-400px. On very narrow screens
the scrollbar now moves all the way to the right instead of
stopping midway.
It's useful for users highlighting with NVDA.
They've to enable native selection and then selection some text.
In this case only a selectionchange is triggered once the selection is done.
Typing in the text field causes a sandbox event to trigger, which we
should await to avoid continuing to the next part of the test before
the sandbox event is fully processed.
