[csswg-drafts] [css-overscroll] overscroll-behavior should not prevent visual viewport "panning" (#12919)

vmpstr has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-overscroll] overscroll-behavior should not prevent visual viewport "panning" ==
If I have a scroller with [overscroll-behavior: contain](https://drafts.csswg.org/css-overscroll/#overscroll-behavior-properties), and I pinch-zoom in (on my macbook), then while my mouse cursor is over this contained scroller, I am unable to pan around the [visual viewport](https://drafts.csswg.org/cssom-view-1/#visualViewport).

This is probably a correct behavior per spec, since the visual viewport refers to scrolling and overscroll-behavior contains the scrolling. This is also reproducible in Safari, Firefox, and Chrome. However, as a user, I find this to be not what I would expect.
