Are timing out on iOS Debug.

History: https://results.webkit.org/?suite=layout-tests&suite=layout-tests&test=fast%2Fselectors%2Fis-backtracking.html&test=fast%2Fselectors%2Fmatches-backtracking.html

Diff:

No diff.

The tests are already marked slow in Bug 139634 and flaky timeout/pass on Mac in Bug 197068.

Tests are already marked as pass/timeout in iOS-14 folder at https://trac.webkit.org/changeset/281858/webkit, but I didn't see any bug that's tracking the tests.

Moved test expectations from iOS-14 to iOS-wk2 and marked as timeout since the timeout is seen on iOS 15 as well.

These tests might be just slow tests. On the history, the tests that were timing out at r281848 took 155 seconds while they are taking only about 35 seconds but still timing out after r281861
Comment 4 ayumi_kojima 2021-10-22 14:44:33 PDT
Removed the test expectations on iOS-wk2 so that the expectation set in Bug 139634 (Slow) will apply to iOS as well.https://trac.webkit.org/changeset/284714/webkit

Tests are timing out after removing timeout expectation. Put it back and continue investigation https://trac.webkit.org/changeset/284790/webkit

I was able to reproduce the timeout at TOT locally on Monterey using run-webkit-tests --force --iterations 50 --exit-after-n-crashes-or-timeouts 1 --debug fast/selectors/is-backtracking.html
