The following layout test is flaky on Mac Debug
imported/w3c/web-platform-tests/IndexedDB/idbindex_openKeyCursor2.htm
Probable cause:
This test began crashing from https://trac.webkit.org/changeset/240358/webkit.
Flakiness Dashboard:
https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=imported%2Fw3c%2Fweb-platform-tests%2FIndexedDB%2Fidbindex_openKeyCursor2.htm
confirmed using command:
run-webkit-tests --root debug-240358 imported/w3c/web-platform-tests/IndexedDB/idbindex_openKeyCursor2.htm --iterations 1000 -f --debug
the test crashes on r240358 but not on r240357.

We already had a bug for this assertion failure. This was a pre-existing bug and r240358 made the bug crash more often so we could observe it on many tests.
