Failure diff looks similar to other fast/events/ios/rotation tests.

On iPhone SE 2nd generation on iOS 15 sim, it reproduced a different diff:

I tried at TOT and the oldest revision available to test, but both produced the same diff. I wonder if this is because this was on iPhone SE 2nd generation. The testing bots seem to be on iPhone SE 1st generation.

fast/events/ios/rotation/layout-viewport-during-safari-type-rotation.html 
is still a constant failure on iOS debug without an expectation set.

[Dawn Morningstar]

Marking expectations for debug queue.

Rebaseline at r294529 did not resolve the issue.  I have marked this test as a flaky failure while this issue is investigated.
