Left column disappear

[ITOjohanhernandez]

Hi, I added a html5 video tag in the right column and it play succesfully, nevertheless if i make full screen with the video when I come back, the left column disappears. If I turn my ipad vertically and I turn it horizontally again, the right column come back. I would like to know how can i prevent this, or how can i make some view refresh to see the left column all the time.
Thankyou
