What steps will reproduce the problem?
(1) Open a Chrome Canary window.
(2) Click the green button to full-screen it.
(3) Visit a video site (e.g., "youtube.com") and play a video.
  - Random video of iguanas: https://www.youtube.com/watch?v=Rv9hn4IGofM
(4) Click the full-screen player button. (Video enters full-screen)
(5) Hit Escape to exit full screen.

What is the expected result?
Browser window goes back into full-screen mode, showing tab bar.

What happens instead?
The tab bar is missing (https://screenshot.googleplex.com/70ScRTb6LaH.png). I have to use the Mac "Exit Full Screen" menu and re-enter full screen before it shows back up.

Please provide any additional information below. Attach a screenshot if
possible.
