I have the problem too. I see the partial box on the left edge of the picture with Firefox 35.0.1. IE puts the box fully outside the picture to the right. Chrome puts the box on the left, same spot as FF, but I can see the whole box hanging over the picture edge rather than cut off. I'm not sure what is up with FF for me. Its been annoying me the last several versions with slowness and other random problems. I've reset it and gone through other troubleshooting, but still getting some strange behaviors.
