Description Ryan Haddad 2017-11-08 16:31:15 PST 
LayoutTest fast/scrolling/rtl-scrollbars.html is a flaky image failure

https://build.webkit.org/results/Apple%20Sierra%20Debug%20WK2%20(Tests)/r224575%20(3918)/results.html

https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=fast%2Fscrolling%2Frtl-scrollbars.html

The image diff shows the scrollbar at the top of the track instead of the bottom.
Comment 1 Ryan Haddad 2017-11-08 16:32:38 PST 
I can reproduce the failure with the following command:
run-webkit-tests fast/scrolling/rtl-scrollbars-text-selection.html fast/scrolling/rtl-scrollbars.html --iter 50 --no-retry-failure
Comment 2 Ryan Haddad 2017-11-08 16:34:33 PST 
I cannot reproduce the failure with a build of r224130, and the earliest failure visible on the dashboard is r224149.
Comment 3 Alexey Proskuryakov 2017-11-09 21:32:19 PST 
I can’t tell which revision between these is the culprit, some more bisecting may be helpful.
