media/video-controls-in-media-document.html is a flaky failure according to the flakiness dashboard. This test was initially reported for failing with multiple other media tests however it has recently been consistently failing with media/video-controls-no-display-with-text-track.html only or on its own. The reverse is also true. There are still examples of these test failing in a much larger block as seen in the original bug: https://bugs.webkit.org/show_bug.cgi?id=173978
