LayoutTest media/modern-media-controls/airplay-button/airplay-button-on.html is a flaky timeout https://build.webkit.org/results/Apple%20Sierra%20Debug%20WK1%20(Tests)/r211039%20(2630)/results.html https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#tests=media%2Fmodern-media-controls%2Fairplay-button%2Fairplay-button-on.html
This appears to be limited to macOS WK1
Marked as flaky in https://trac.webkit.org/changeset/211073
I've been unable to reproduce the flakiness locally. I've tried with the latest timeout on Sierra WK1 Debug (https://build.webkit.org/builders/Apple%20Sierra%20Debug%20WK1%20(Tests)/builds/2852) but the test passed. I then tried 500 iterations of this test alone on the same configuration, and it wouldn't fail a single time.
This still times out occasionally.
