These are reproducible on Sonoma Release ToT running the test as follows:

run-webkit-tests <insert_test_here> -1 --force


Expectations are already set for these tests because they were having a negative impact on EWS.

In looking back in the history link these have been constant failures on macOS WK1 only for as far back as I could scroll (50,0000 commits)
