 Replying to [comment:2 mindrun]:

 > Oh, sorry. I forgot to explain, why I also changed the z-index property
 to `9980`. This change is required to avoid that the content is pushed
 between `#adminmenuback` and `#adminmenuwrap` if the user scrolls to the
 right.

 Thanks for following up. I thought I had checked for that, but guess I
 didn't scroll far enough to see it. [attachment:30900.2.diff] updates the
 needed z-index property accordingly.
