I have marked this test as flaky timing out and crashing while this issue is investigated.

I don't see any crashes on Mac, there are only iOS ones from a recent regression (hasInitializedAppBoundDomains).

Seems almost certain to have started with r259463.

After https://trac.webkit.org/changeset/260130/webkit, the test switched from timing out to failing on mac-w1 debug.

Updated mac-wk1 expectations in https://trac.webkit.org/changeset/260272/webkit

Comment 6 Jason Lawrence 2020-05-11 07:44:13 PDT

I have removed the expectations because this test appears to be passing consistently now.
