The timeout is showing up on EWS as a flaky test. Updated test expectations while investigating to speed up EWS: https://trac.webkit.org/changeset/282104/webkit

The timeouts initially started with https://trac.webkit.org/changeset/281981/webkit

Marked test expectations to pass/ fail for Mac-wk1 and removed pass/timeout from iOS-wk2 and Mac-wk2 because the test is no longer timing out: https://trac.webkit.org/changeset/282394/webkit
