Bug 240659

Created attachment 459594 [details] 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.
