Repro steps:

1- Go to https://scroll-snap-demo.web.app/
2- Scroll past the results (~3500px on iPhone XR)
  2.a- When you reach colorful sections, you should start noticing CSS scroll snap points.
3- Scroll to go to next colorful section.
4- Before scroll snap is complete, *tap* anywhere on the screen.

Actual Behavior on Safari 16 in iOS:
- Tapping interrupts scroll snapping, and causes scrolling to jump, restoring the original position before any scrolling happened.

Expected behavior:
- Tapping should not cause any scrolling position to change
