CRASH LOG URL (raw JSON, parsed attached):



I was unable to reproduce this issue on the reported platform using run-webkit-tests. I will do some more testing to attempt to reproduce the issue.


I believe the regression point is at 267014 at main, as this is the first crash instance and appears to have changes directly related to the subject of this test.
