Created attachment 468374 [details] Crash log Whenever I slide the video scrubber to the end of the video and then hold my finger at the end as the video automatically closes, Safari crashes. Steps to Reproduce: 1. Open Safari 2. Go to https://www.apple.com/apple-events/ 3. Tap on the first event there with the text “Watch the recap” 4. Slide the video scrubber all the way to the end of the video and hold the finger there 5. Watch safari close the video automatically and then crash Expected Results: Video scrubber remains in place and only repositions itself right before the end of the video when the scrubber is released from being held, which keeps the video open and avoids a crash Actual Results: Safari closes video while user is holding the video scrubber and then Safari crashes.
