I was able to replicate this failure on Ventura ToT as follows:

run-webkit-tests --root imported/w3c/web-platform-tests/css/css-cascade/layer-counter-style-override.html


I also noticed failures on iOS. These appear to be expected failures.

Comment 3 Bri Harris 2023-04-10 10:37:23 PDT

This tests appears to have been flaky for a long time. It does appear that the failures became consistent on macOS at 262309@main, which deals with CSS changes.

Test gardening commit 262775@main (3b2ddab9ecc8): <https://commits.webkit.org/262775@main>

Reviewed commits have been landed. Closing PR #12576 and removing active labels.

Comment 6 Ryan Haddad 2023-04-17 16:35:32 PDT

This looks like a progression, since a previously failing subtest is now passing on Ventura. We might want to land a rebaseline for mac-wk2 (which might require adding a new baseline in platform/mac-monterey)

Comment 7 Ryan Haddad 2023-04-24 16:35:00 PDT

https://commits.webkit.org/263127@main re-baselined this test but did not remove the test expectation.
