Topic: Back button behaviour with Full Screen
JB is 100% x 100% with Use Fullscreen Expand enabled
When in Full Screen and click back button you exit Full Screen and go to the back button url - fine
Problem is if you then go back to the JB gallery, it is still scaled for Full Screen - It's not returned to viewport scale.
Requires refresh but looks like an error.
Suggest back button is hidden in Full Screen to avoid this.
User would then return JB to viewport before clicking back button.
(Chrome doesn't give this problem - it reloads JB page when you go back to it, but Safari, Firefox IE and Opera where giving the error for me)
EDIT
Also I think its best to exit Full Screen before navigating to a new page - more logical I think.
Best to enter and exit Full Screen from the JB full viewport page - then navigate back.
Again, hiding Back button in Full Screen would be better I think
