LayoutTest editing/selection/move-by-word-visually-multi-space.html is timing out https://build.webkit.org/results/Apple%20iOS%2011%20Simulator%20Debug%20WK2%20(Tests)/r224349%20(799)/results.html https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=editing%2Fselection%2Fmove-by-word-visually-multi-space.html This test always takes 32-35 seconds to complete on this queue, so it frequently times out.
By "this queue" I meant iOS Simulator Debug WK2.
Skipped test in https://trac.webkit.org/changeset/224365/webkit
The first timeout visible on the dashboard for this queue is @ r223736 on 10/19/2017.
This test just takes close to 30 seconds when it doesn't fail. Not sure if it's actually testing the right thing on iOS, but one other possible response is to mark it as slow.
I now see that you already observed that.
