I was able to reproduce this at Ventura ToT running the test as follows: run-webkit-tests imported/w3c/web-platform-tests/css/css-tables/visibility-collapse-row-003-dynamic.html --iterations 100 This test has been in this state since it was re-imported/resynced at https://commits.webkit.org/264228@main
