Attachment: Bug 1861378 - Remove unnecessary meta annotations on linux for /css/css-contain/content-visibility/animation-display-lock.html

There is a meta annotation for animation-display-lock.html on linux, but the test works completely now.
This patch removes the unnecessary meta annotations

Comment 5

[Frédéric Wang Nélar]

I've tried to reproduce locally playing with --enable-optimize --enable-debug build config --rerun, --verify-chaos-mode and --debugger=rr and failed to do so.

Comment 4 shows a recent failure in debug build (not covered by existing annotation)

So not sure what to do here.

Comment 7

[Frédéric Wang]

Last failure (not covered by current animation-display-lock.html.ini) happened with linux1804-64-qr debug no-fission on 2023-11-16. It's possible that this was fixed by most recent changes. As I suggest in bug 1785541 comment 49, we can probably land Jihye's patch and see whether the intermittent failures starts showing up again (assuming this is the usual way to handle this kind of failures).

(In reply to Frédéric Wang from comment #7)

As I suggest in bug 1785541 comment 49, we can probably land Jihye's patch and see whether the intermittent failures starts showing up again (assuming this is the usual way to handle this kind of failures).

I stand corrected. I can reproduce locally with a non-optimized release build with

./mach wpt --rerun 10 --verify-chaos-mode --pause-on-unexpected --debugger=rr /css/css-contain/content-visibility/content-visibility-auto-relevancy-updates.html /css/css-contain/content-visibility/content-visibility-vs-scrollIntoView-003.html /css/css-contain/content-visibility/content-visibility-vs-scrollIntoView-002.html /css/css-contain/content-visibility/animation-display-lock.html /css/css-contain/content-visibility/slot-content-visibility-8-crash.html /css/css-contain/content-visibility/content-visibility-resize-observer-no-error.html

and with a debug build with too.

./mach wpt --rerun 10 /css/css-contain/content-visibility/content-visibility-auto-relevancy-updates.html /css/css-contain/content-visibility/content-visibility-vs-scrollIntoView-003.html /css/css-contain/content-visibility/content-visibility-vs-scrollIntoView-002.html /css/css-contain/content-visibility/animation-display-lock.html /css/css-contain/content-visibility/slot-content-visibility-8-crash.html /css/css-contain/content-visibility/content-visibility-resize-observer-no-error.html
