Issue 913955: [CompositeAfterPaint][css-scroll-snap] Fix scroll snapping for SPV2

Reported by sunyunjia@chromium.org, Dec 11 Project Member

Issue description

Some layout tests for scroll snapping are failing when SPV2 is enabled, such as snaps-after-scrollbar-scrolling.html and snaps-after-keyboard-scrolling.html. We should figure out the reason for the failures and fix them.

After triage, only one test left for this bug:
 fast/scroll-snap/snap-scrolls-visual-viewport.html

Other failures under fast/scroll-snap are because of  bug 920224  and  bug 921194 .
