Description:
tiled-drawing/scrolling/scroll-snap/scroll-snap-mandatory-async-overflow.html is a consistent crash

The test was consistently passing until range https://commits.webkit.org/compare/263108@main...263104@main.  The assertion references changes like setNodeScrollSnapInProgress made in https://commits.webkit.org/263108@main, making it the likely culprit.

This issue can be reproduced using command:
run-webkit-tests --exit-after-n-failures 1 --exit-after-n-crashes-or-timeouts 1 --iterations 1 --no-retry-failures --use-gpu-process --remote-layer-tree  tiled-drawing/scrolling/scroll-snap/scroll-snap-mandatory-async-overflow.html
