Comment 2 Ryan Haddad 2020-12-01 09:45:44 PST

I can reproduce the flaky timeout locally with the following with a build of r270132:
run-api-tests TestWebKitAPI.TextManipulation.StartTextManipulationAvoidCrashWhenExtractingOrphanedPositions --debug --iterations 10

I cannot reproduce the timeouts with a build of r270131.
