Add -webkit-overflow-scrolling: touch?

[stevemao]

when you have something like overflow: auto;, on desktop browsers and Android the scroll is natural. Only on iOS it stops scrolling immediately when you release your finger. According to mdn, -webkit-overflow-scrolling is not standard so I feel like this is a missing default feature on iOS.

Where would you add it?

There must be a reason why it's a CSS property and not just on by default. This will require more research.

For example, some potential gotchas:

  (These are old issues, but no mention whether they're solved in later iOS versions)
