Apparently Gerrit UI is crashing mobile safari now, urls like https://review.opendev.org/c/openstack/ansible-role-collect-logs/+/787502 or other spcific reviews seems to just crash the page loading. Mobile chrome is not affected, only safari, iOS 14.7. How can I get more info about what is really causing the crash?

As of 2022-04, they recommend setting "v=spf1 include:icloud.com ~all", so which is bit different than the redirect= variant from original report. I am not sure if this changed or if both are ok but worth mentioning.
