The test media/video-load-preload-metadata.html is a flaky failure on iOS simulator WK2 according to the dashboard. https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=media%2Fvideo-load-preload-metadata.html https://build.webkit.org/builders/Apple%20iOS%2010%20Simulator%20Release%20WK2%20(Tests)/builds/3748 https://build.webkit.org/results/Apple%20iOS%2010%20Simulator%20Release%20WK2%20(Tests)/r220980%20(3748)/results.html This doesn't appear to be a recent regression. The test was previously flaky with on macOS and was marked as such, but has since started on iOS Simulator as well.
