This also happens on Sierra. Updated TestExpectations in https://trac.webkit.org/r227250.

This has started failing consistently on iOS 11 Simulator but has since started to pass on macOS:

https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=webrtc%2Fvideo-mute.html

Strangely, There is no diff for the test.
