Steps to reproduce: 1. on iPad, load apple.com/events 2. play the latest event 3. Scrub forward 4. Wait a bit to see the buffered data indicator (the gray-ish bar showing data buffered ahead of the play head) fill up 5. Scrub backward At this point you'll notice the buffered data indicator lingers up to the point where you were playing prior to scrubbing and only snaps back after playback resumes at the new play time.
