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.

I've tested by reverting my CL in https://chromium.googlesource.com/chromium/src/+/1bb05e1810bb6117d6e091ceefe3b4ea17572971 and the problem still occurs, so Predator has identified the wrong CL.
