 Replying to [comment:1 joemcgill]:
 > Confirmed that this is a bug and changing the position property from
 `absolute` to `fixed` fixes the issue. There's no need, as far as I can
 tell, to change the z-index for this to work, so I've left that alone in
 [attachment: 30900.diff].

 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.

 Here's another quick shot without the new z-index:
