Fullscreen getting cut off (by another element?)

[Russinating]

If you go to jonesmillbank.com/what-we-do/google-business-view, and double click the image it should go full screen, but the right half is cut off. I've looked with Developer Tools in Chrome and can't see what element is blocked/cropping this off? Anyone have any ideas?

Thanks, helps! That bit is written by the Pano2VR JS code but weirdly though fullscreen works when the pano is output by it raw, it's only when I put it into this site that it decides to write that value as -451px instead of 0. Can't find any instance in my site's CSS or anywhere to that value so I'm a bit stumped!

Fixed, ta!
