Marked test expectations: https://trac.webkit.org/changeset/283640/webkit

I reproduced the failure easily at TOT and the oldest spades available to test on iOS 15 sim using run-webkit-tests --force --ios-simulator --iterations 50 --exit-after-n-failures 1 fast/events/ios/rotation/safe-area-insets-during-safari-type-rotation.html
