After reviewing the dashboard, this appears to have regressed at 251589 (https://trac.webkit.org/changeset/251589/webkit).  

I am able to reproduce the flaky failure locally with run-webkit-tests iterations.

Also, bug 206935 has been marked as a duplicate of 206396.

Comment 11 Chris Dumez 2020-01-31 16:23:21 PST 
Flakiness dashboard shows one timeout after this fix so this fix does not appear to be sufficient. Reopening.
Comment 12 Jason Lawrence 2020-02-11 14:44:33 PST 
I have marked this test as failing while this issue is investigated further.
