The following layout test is failing on Mac WK2

storage/indexeddb/modern/transaction-scheduler-3-private.html

Probable cause:

Is a very flaky failure from the oldest build I can spade (228049) to current.

Reproducible with: 

run-webkit-tests t195394 storage/indexeddb/modern/transaction-scheduler-3-private.html --iterations 5000 -f --exit-after-n-failures=1 --no-retry-failures
