Crash Log

Description:
fast/text/isolate-ignore.html

The first failure that I saw on the dashboard was on 4/1/2022 at r292225, but this does not appear relevant to causing this issue. This test has been a flaky and then consistent crash for its entire history on the dashboard.

History:
https://results.webkit.org/?suite=layout-tests&test=fast%2Ftext%2Fisolate-ignore.html&platform=ios&limit=50000&style=debug

This started between 2022-03-23 and 2022-03-28. It was flaky at first, but crashes every time now.

Maybe http://trac.webkit.org/r291751, DOM in GPU Process?
