[Matt Lewis]

media/event-queue-crash.html is a flaky failure on macOS. According to the dashboard it has flaked on High Sierra Release, Sierra Debug WK1, and El Capitan Release WK2:

https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=media%2Fevent-queue-crash.html

https://build.webkit.org/results/Apple%20High%20Sierra%20Release%20WK2%20(Tests)/r225575%20(1576)/results.html
https://build.webkit.org/builders/Apple%20High%20Sierra%20Release%20WK2%20(Tests)/builds/1576

There isn't a clear regression point on the dashboard.

Matt, is this reproducible?

[Matt Lewis]

Yes, I was able to reproduce the failure on High Sierra however I had to run this multiple times to get the failure:
run-webkit-tests media/event-queue-crash.html --no-retry-failure --verbose --iterations=50 -f -g
