fast/loader/redirect-to-invalid-url-using-meta-refresh-calls-policy-delegate.html is flaky failing and was first seen on commit 252050 but not sure if that is the origin. I did not try to reproduce the failure, it is happening on macOS wk1.

Note, this test must be run in DumpRenderTree.
<rdar://problem/58837324>
This test does reproduce easily by running it in iterations. It reproduces on much older builds than the suggested regression point so I still cannot tell when this may have started.
Looking at this example: https://build.webkit.org/results/Apple-Catalina-Debug-WK1-Tests/r254577%20(1809)/results.html The line that is missing in the diff for fast/loader/redirect-to-invalid-url-using-meta-refresh-calls-policy-delegate.html is unexpectedly present in the diff for fast/loader/redirect-to-invalid-url-using-meta-refresh-disallowed-async-delegates.html In every failure I looked at, both tests fail together as described above.
