This is not a duplicate.

Comment 4 ayumi_kojima 2021-10-20 15:47:19 PDT

I was albe to reproduce the failure locally using run-webkit-tests --force -1 --iterations 50 --exit-after-n-failures 1 imported/w3c/web-platform-tests/html/semantics/selectors/pseudo-classes/focus-autofocus.html

The test failed with r283938 and passed with r283934 (No revisions to test in-between).

Seems like either https://trac.webkit.org/changeset/283935/webkit or https://trac.webkit.org/changeset/283938/webkit caused the flaky failure.

Never mind. It looks like this is a duplicate of Bug 231918 after all.
