The test checks as close as possible to the auto-hide delay that the controls are still visible, and then again as soon as possible after the auto-hide delay has elapsed to check that the controls are no longer visible. So in certain cases, probably where the system is under pressure and timers run late, we get in cases where the check prior to the timer firing fails because we've actually run past auto-hide delay. We're going to have to find a different way to test this. 1271649 3 graouts 2017-01-31 03:01:01 -0800 Committed r211424: <http://trac.webkit.org/changeset/211424> 1271866 4 ryanhaddad 2017-01-31 13:40:14 -0800 Just saw this fail again: https://build.webkit.org/results/Apple%20Sierra%20Release%20WK1%20(Tests)/r211438%20(3272)/results.html 1271898 5 ap 2017-01-31 14:32:06 -0800 This test has 300ms timeouts.

Clearly it does the majority of the time.
