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.

Perhaps caused by a preceding test? Seems unlikely that this code gets triggered as part of generic layout test execution.
