Description Zouhir 2023-03-01 14:37:56 PST

iOS: 16.3.1
Safari: 16

Repro steps:
(1) Go to https://scroll-snap-demo.web.app/ on mobile device.
(2) Try scrolling down.

What is the expected result?
- When a snappable section is taller than the viewport, it's expected to have natural / smooth scrolling while scrolling through that section.

What happens instead?
- Scrolling on mobile is not smooth / have no momentum. Safari on desktop seems better.
