fix(multiple): remove webkit-overflow-scrolling (#30003)

This is a non-standard CSS property that only works on mobile Safari and
may cause inconsistent behavior by introducing a new stacking context.
Users who want this behavior can add the property themselves, but we
shouldn't specify it by default.

fixes #19374
