Comment 3 Robert Jenner 2023-02-27 16:14:34 PST

I was able to reproduce the failures and timeouts at iOS Debug ToT running the tests as follows:


run-webkit-tests --ios-simulator <test_name_goes_here>


I was also able to confirm a regression range. The tests passed at 260772@main, and failed at 260774@main. Indicating that the regression point is either 260773@main or 260774@main. Judging by the changes in 260773@main only being changes to macOS code, it would appear that 260774@main is our regression point here.
