I was able to reproduce this bug on macOS Ventura using arm64 running the test as follows:

run-webkit-tests -1 http/tests/media/hls/track-in-band-multiple-cues.html --iterations 10

Using the flakiness dashboard, I was able to identify that the regression point appears to be the test's introduction to the project at 264554@main. This may also be a problem with DumpRenderTree on WK1, so I have linked a similar issue (https://bugs.webkit.org/show_bug.cgi?id=259482).

Correction: the regression is 266260@main, not 264554@main (typo).

I have marked this test as a flaky failure while this issue is investigated. (Link: https://github.com/WebKit/WebKit/pull/16073)

Correction: I have marked this test as a **constant crash** while the issue is investigated.
