REPRODUCIBILITY:

I was able to reproduce this issue on macOS Ventura (13.5, 22G74/arm64) ToT using the following command:

run-webkit-tests --debug --verbose --clobber-old-results --iterations 10 inspector/timeline/timeline-event-CancelAnimationFrame.html inspector/timeline/timeline-event-performance-mark.html inspector/timeline/timeline-event-RequestAnimationFrame.html

REGRESSION:

A related bug (bug #260360) indicates that the regression point for a similar issue is 263917@main. Due to build failures, I'm unable to bisect around this point; however, contextual information indicates that this issue likely has the same regression point.

NOTE:

There are already test expectations filed for multiple tests in the inspector/timeline directory.

In all cases, the failure is caused by a timeout.
