This test is actually flaky on all Mac WK1 platforms and only on Debug WK2 per the flakiness dashboard. Right now test is marked as failure on windows in the expectations. However the release wk1 have only recently started to fail intermittently as of 5/22/17. Test was originally brought in with this revision: https://trac.webkit.org/changeset/213882/webkit

Looking at the flakiness dashboard, it's very flaky, and it's affecting CQ/EWS. Could you please add an expectation?
Marked the test as flaky https://trac.webkit.org/changeset/218104/webkit/
