Automatically assigning owner based on suspected regression changelist https://chromium.googlesource.com/chromium/src/+/705775845f6e50a89bc4bad7a2a18126d936c655 (Make PlatformPaintWorkletInput take a FloatSize).

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.

The PlatformPaintWorkletInput data structure isn't used anyway, so that can't be the reason.

Stack overflows are P2. Maybe one for chrishtr@, or at least to re-assign.
