The new failures are due to the fact that the cssom-view test suite has been moved into wpt/css (I did not notice it because the old version is still present). See bug 189241.

Note that I only moved existing code from HTMLBodyElement.cpp. Maybe these changes should be handled separately to make them clearer in the history.

I think it's OK to do a refactor when moving code.

All reviewed patches have been landed. Closing bug.

<rdar://problem/44237945>

Looks like this patch https://trac.webkit.org/changeset/235806/webkit has caused https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=tiled-drawing%2Fscrolling%2Ffast-scroll-iframe-latched-mainframe.html to become flakey timeout. Test History: https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=tiled-drawing%2Fscrolling%2Ffast-scroll-iframe-latched-mainframe.html I reproduced this flakiness using command: run-webkit-tests tiled-drawing/scrolling/fast-scroll-iframe-latched-mainframe.html --iterations 500 -f on a build of 235805 and no timeouts occurred. running this on 235806 and the failure reproduces easily.

(In reply to Truitt Savell from comment #51) > Looks like this patch https://trac.webkit.org/changeset/235806/webkit Thanks, I wonder whether it's related to the current implementation of Document::isBodyPotentiallyScrollable (see bug 182292). I guess a workaround for now would be to use documentElement instead of scrollingElement in LayoutTests/tiled-drawing/scrolling/fast-scroll-div-latched-mainframe.html

I thought the issue was with tiled-drawing/scrolling/fast-scroll-div-latched-mainframe.html... For fast-scroll-iframe-latched-mainframe.html, just replacing document.body with document.scrollingElement avoids the flackiness for me.
