REPRODUCIBILITY:

I was able to reproduce this issue on macOS Ventura (13.5, 22G74/arm64) ToT using the following command:

run-webkit-tests --clobber-old-results --verbose --iterations 10 --exit-after-n-failures 1 fast/scrolling/mac/programmatic-scroll-overrides-rubberband.html

REGRESSION:

I was able to bisect a likely regression point at 268267@main; changes appear to be directly related to this issue, and the issue did not reproduce before that point.
