This test was re-enabled in December and has been passing consistently up until yesterday. The test is now frequently timing out on Sierra, seemingly after https://trac.webkit.org/changeset/228252/webkit

After skipping this test, another test has started to be a flaky timeout:

This test is also a flaky timeout in GTK, but is hard to reproduce.
It happens much often on the bot which runs with the flag --skip-failing-tests ( see bug 227744 ).. that may indicate the flakiness can be related by a previous test scheduled on the worker that leaves WTR in an unexpected state.
