Automatically assigning owner based on suspected regression changelist https://chromium.googlesource.com/chromium/src/+/8ec63cd6d0aaf1b5be1ded592d0d7b5263d31a29 (SharedWorker: Treat worker script on file:// URLs as opaque origins).

If this is incorrect, please let us know why and apply the Test-Predator-Wrong-CLs label. If you aren't the correct owner for this issue, please unassign yourself as soon as possible so it can be re-triaged.

I don't think this is related to my change because the minimized test case doesn't use shared workers.

Added the Layout components based on the stack trace.

This issue looks similar to   bug 842159 , hence assigning to the same owner for more updates.

mfoltz@ Could you please take a look in to this issue?

Thanks!

Labels: Needs-Feedback
ClusterFuzz testcase 5532281142509568 is still reproducing on tip-of-tree build (trunk).

If this testcase was not reproducible locally or unworkable, ignore this notification and we will file another bug soon with hopefully a better and workable testcase.

Otherwise, if this is not intended to be fixed (e.g. this is an intentional crash), please add ClusterFuzz-Ignore label to prevent future bug filing with similar crash stacktrace.
