Comment 3 Robert Jenner 2023-05-25 10:25:07 PDT
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

Test gardening commit 264525@main (283047c0aa40): <https://commits.webkit.org/264525@main>

This is probably a duplicate of Bug 8735
