Steps to reproduce the problem:
1. Maximize the app (full screen)
2. Ctrl F in any page 
3. Press Esc (escape key)
4. The browser returns to a "normal" windowed mode

What is the expected behavior?
1. Maximize the app (full screen)
2. Ctrl F in any page 
3. Press Esc (escape key)
4. Close the search box

What went wrong?
This behaviour has changed since the last version. It's not the expected behaviour, especially if your search happens to find results and higlight, then you can only cancel by using the mouse.

Did this work before? Yes last version

Chrome version: 53.0.2785.116  Channel: stable
OS Version: OS X 10.12.0
Flash Version: Shockwave Flash 23.0 r0

I believe that this has happened it other versions as well, about 6 months ago I think.
