I was unable to reproduce this crash on macOS Ventura, instead getting a timeout (see bug #259546 for more information). This may indicate a larger problem with the testing bot itself. Further investigation is needed.

I have marked this test as a constant crash/timeout while this issue is investigated. (Link: https://github.com/WebKit/WebKit/pull/16129)

REGRESSION: While this test was a flaky/consistent crash before 266513@main, it further regressed to constant at 266513@main.
