Steps to reproduce the problem:
1. Open a remote video that uses chrome's native video player (e.g. open an .mp4 file from a remote location in a tab)
2. Pause the video quickly
3. Don't move the mouse

What is the expected behavior?
The dark-gray background of the position slider, which indicates the buffer progress, continuously grows as more of the video is downloaded.

What went wrong?
The buffer indicator is not updated.

Did this work before? N/A 

Chrome version: 51.0.2704.84  Channel: stable
OS Version: 
Flash Version: Shockwave Flash 21.0 r0

The buffer indicator is updated whenever you move the mouse over the video element and once it's fully buffered. This issue is only about the UI not being redrawn automatically.
