Automatically assigning owner based on suspected regression changelist https://chromium.googlesource.com/chromium/src/+/1bb05e1810bb6117d6e091ceefe3b4ea17572971 (OOPIFs shouldn't invoke snap-to-min on PinchEnd.).

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.

Comment 5 by ClusterFuzz, Nov 15

Labels: Needs-Feedback
ClusterFuzz testcase 6351414608265216 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.
