Steps to reproduce the problem:
1. chrome.windows.create({type: 'popup', state:'fullscreen', tabId: 1234, incognito: false});
//Existing tab should now be a fullscreen window
2. Pressing F11 will cause this fullscreened popup to become a black screen. The task still exists in the Task Manger but the window cant be closed without finding the task and ending it manually.

What is the expected behavior?
Fullscreen should have been successfully exited, and window should still be a popup just in a smaller size (or its previous dimensions if applicable).

What went wrong?
I was able to work around the issue by creating the window in a maximized state and then calling update to change it to fullscreen. After doing that, the issue doesn't present itself (but causes a small screen flicker for the user so it's not ideal). I assume there's some logic that is expecting a popup window to have started off in a normal state before pressing F11 to exit the fullscreend state. (but I don't really know. see attached demo) 

Did this work before? N/A 

Does this work in other browsers? N/A
