Steps to reproduce the problem:
1. Auto-hide the Windows task bar
2. Open an HTML 5 video - YouTube/Twitch
3. Go Full screen
4. Exit Full screen
5. Task bar stays hidden instead of re-taking priority over Chrome

What is the expected behavior?
Once the full screen application is closed (no longer full screen) the Windows task bar should be accessible by hovering your mouse over it.

What went wrong?
I believe Chrome is keeping priority over the Windows task bar even after the full screen application is left.

Did this work before? Yes Not sure of the version - Bug has been happening for maybe a week or two.

Chrome version: 51.0.2704.63  Channel: stable

Dual monitor setup - possibly related to issue 604359.  If you minimize the Chrome window entirely, you can temporarily make it function as normal, until you open another full screen video.
