Comment:

 I can't reproduce either.

 The thickbox overlay and the thickbox modal (which is what you're seeing
 in all of your screenshots) have the same index, and your patch changes
 both of them, which wouldn't have any effect on the modal displaying in
 front of the overlay. The modal element is after the overlay, which is why
 it's always displayed on top of the overlay when they have the same index.
 Changing the `z-index` here would cause issues with the overlay and modal
 displaying behind other elements of the admin, as noted in the css inline
 comments, and shouldn't fix the issue you're seeing. Most likely there's a
 plugin conflict.
