It looks like the changes in https://trac.webkit.org/changeset/244098/webkit are most likely responsible for the test fast/dynamic/paused-event-dispatch.html becoming a timeout. History: https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=fast%2Fdynamic%2Fpaused-event-dispatch.html build: https://build.webkit.org/builders/Apple%20Mojave%20Debug%20WK1%20(Tests)/builds/2992

We were able to reproduce this failure using command: run-webkit-tests fast/dynamic/crash-subtree-layout-when-auto-size-enabled.html fast/dynamic/paused-event-dispatch.html -1 --no-retry running the test fast/dynamic/crash-subtree-layout-when-auto-size-enabled.html, added in 244098, in front of the timing out test causes the timeout.

Ok. Thanks! I'll look into it.
This patch actually revealed a bug in the test framework. We don't reset the auto-sizing mode for subsequent runs.
