This test is a flaky failure on iOS bots, with the first failure appearing to be with https://trac.webkit.org/changeset/238667/webkit (though the revision itself appears to be unrelated).
The test was added with the service-worker WPT resync in https://trac.webkit.org/changeset/238592/webkit
Marked test as flaky on iOS in https://trac.webkit.org/r239450
