Nightly from a few days ago. STR: - Open a video, e.g. http://media.grabaperch.com/video/perch2/perch2home.ogv (doesn't matter if it's embedded or direct) - Start it playing, click the speaker icon to mute - Click on the time bar to seek to another time - Video becomes unmuted, though the speaker icon still shows 0. You have to click it twice to get it to mute again. - Seek again, it becomes unmuted. Expected results: Video should stay muted after seeking.
