I believe the test started failing on iOS 15 because it was passing on iOS 14 when I looked at the history earlier.

Marked expectations https://trac.webkit.org/changeset/283621/webkit

I was able to reproduce the failure locally on iOS 15 sim (iPhone SE 2nd generation) using run-webkit-tests --force --ios-simulator fast/events/ios/rotation/safari-like-rotation.html

But the diff I got was different from the test run.

The test also failed with the oldest revision available to test (r265703).

Updating the title accordingly.

Reverse duping this to bug #275696 / rdar://130212796, as it includes more tests that appear to have the same issue.
