Description Brent Fulgham 2015-05-08 22:53:12 PDT

Add tests to confirm that the scroll snap logic properly handles the following:
1. Inserting/removing elements into an existing scrollable region with snap points.
2. Marking elements 'display:none'

Comment 1 Brent Fulgham 2015-06-16 14:30:58 PDT

Also:

3. programmatically change overflow:scroll on ancestors of scroll-snap-coordinate elements

4. Snapping after layout changes

Chrome does this now: https://web.dev/snap-after-layout/

I believe that 1, 3, and 4 are currently covered, but there are no tests to check the behavior of css-scroll-snap when elements have 'display:none'.
