This test is exercising content-visibility:hidden
, which we don't yet implement.

Reopening; we've enabled content-visibility
on Nightly but we still have a failure in this test:
https://wpt.fyi/results/css/css-contain/content-visibility/animation-display-lock.html
Our .ini file seems to have it annotated as random, specifically on linux 64-bit opt:
https://searchfox.org/mozilla-central/rev/e6a03adbf7930ae0cf131cc3274c80b2aae74e51/testing/web-platform/meta/css/css-contain/content-visibility/animation-display-lock.html.ini
if (os == "linux") and not debug and fission and (processor == "x86_64"): [PASS, FAIL]
I'm not sure why we would only fail that in a Linux-specific way. I see the exact same test failure when I run the test in macOS Nightly, FWIW.
Note, I think "display lock" here is really talking about an element that is "skipped" from a content-visibility perspective. It looks like there's some subtlety about handling transitions and animations in such subtrees; https://drafts.csswg.org/css-contain-2/#cv-notes step 9 covers some of it. From a quick skim, it looks like style-queries are still supposed to cause animation events to be dispatched in some cases, but I'm not sure yet if the test's style-queries should be sufficient to trigger that or not.
