Description:
http/tests/quicklook/same-origin-xmlhttprequest-allowed.html

This test is constant failing one [ iOS Release ] and constant crashing on [ iOS Debug ].  The first failure that I saw on the dashboard was 4/26/2022 r293432, but does not seem relevant. 

Commit r293427 at Canonical link: https://commits.webkit.org/249987@main | git-svn-id: https://svn.webkit.org/repository/webkit/trunk@293427 268f45cc-cd09-0410-ab3c-d52691b4dbfc modified some files that seem to have introduced the constant failures and crashes.
