It either snaps to the top left of the screen (instead of lining up with the surface), or it tries to render with 0 width (especially if you switch page)
I can't find a cause using git-bisect. VisualEditor.git goes back to 20 Dec 2013, which already exhibits the problem. Bisecting in mediawiki/extensions/VisualEditor.git also led to nothing as the problem was never present there to begin with. I suspect the problem may be caused by us having removed a stylesheet in the repo split that is now in the ve-mw only, but should be under ve/ve instead.
