Comment 3 Bri Harris 2023-01-23 14:46:01 PST 
Test is flaky; However, I was able to reproduce crash on iOS 16 Debug ToT running the test as follows:

Run-webkit-test --iOS-simulator fast/forms/ios/remove-view-after-focus.html --iteration 100

Running in iterations of 100 allowed us to reproduce the crash more than once during that test run.

It appears to have been a flaky crash since testing began on iOS 16.

Comment 9 Alexey Proskuryakov 2023-01-24 18:58:23 PST 
Perhaps caused by a preceding test? Seems unlikely that this code gets triggered as part of generic layout test execution.
