This new patch goes further down the same path, cleaning up a lot of cruft in the scrolling tree.

Duplicate change
Comment 20 Truitt Savell 2019-02-27 15:39:32 PST 
The changes in https://trac.webkit.org/changeset/242132/webkit

has caused tiled-drawing/scrolling/scroll-snap/scroll-snap-proximity-mainframe.html

to start timing out flakily.

History:
https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=tiled-drawing%2Fscrolling%2Fscroll-snap%2Fscroll-snap-proximity-mainframe.html

reproduced with: 
run-webkit-tests tiled-drawing/scrolling/scroll-snap/scroll-snap-proximity-mainframe.html --iterations 200 -f

this test times out on r242132 but not on r242131.
