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.

Flakiness dashboard shows one timeout after this fix so this fix does not appear to be sufficient. Reopening.

I have marked this test as failing while this issue is investigated further.

I have removed the expectation that was previously set when there was an issue.
