I have marked this test as crashing while this issue is investigated here: https://trac.webkit.org/changeset/258000/webkit
https://trac.webkit.org/changeset/258001/webkit
Comment 2 Jason Lawrence 2020-03-06 09:46:42 PST
Reverted r258001 for reason:

I inadvertently changed the wrong expectation in this commit.

I am able to reproduce this issue with r257235 by running the command below, but cannot reproduce the issue with r257234.
