Automatically assigning owner based on suspected regression changelist https://chromium.googlesource.com/chromium/src/+/0aca50f1552c882bc72ed5c419085fa975847a9c ([Squad] Unnecessary use of mutable style in vp propagation.).

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.

There's a deep layout stack here.

Unable to find actual suspect through code search and also from the provided CL under regression range, hence adding appropriate label and leaving it as untriaged for further updates.

Thanks!

Labels: Needs-Feedback
ClusterFuzz testcase 5818259270795264 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.
