media/track/track-cue-rendering.html was always flaky, but lazy tree creation made it so that it fails nearly every time on debug bots: http://webkit-test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=media%2Ftrack%2Ftrack-cue-rendering.html
This test was removed in this commit: https://github.com/WebKit/WebKit/commit/a39bd42ad87d82a3bea0fa6eac107376a973cf7c Nothing to do here, changing to 'RESOLVED CONFIGURATION CHANGED'.
