I can reproduce this using command:

I am unable to make a proper bisection at this time due to some oddness with run-webkit-tests that we are looking at in another bug.

Looking at test history, https://trac.webkit.org/changeset/280722/webkit seems to be a candidate. This was certainly not failing before August 1, 2021

This test started showing up on macOS-Catalina-Release-WK2-Tests-EWS as flaky tests.

Updated the test expectations to speed up EWS https://trac.webkit.org/changeset/281517/webkit
