This test run has an example of both tests failing

I haven't been able to pinpoint an exact regression point, so I have marked both tests as flaky in <http://trac.webkit.org/projects/webkit/changeset/200256>

But is it still a regression, even though we don't know when exactly this started?

The tests were not flaky on Mac until 2 days ago. I am working to find the commit that caused the regression.

<http://trac.webkit.org/changeset/200150> seems to be the culprit (Thanks, Alexey)
