(setq special-display-regexps (list "^\\*"))

Split the window (into A and B).

Type `C-h f quit-window' in window A. See the new frame pop up, and the 
windowing system switch to it.

Press `q', the new frame is buried, focus returns to A.

Switch to B. Type `C-h f car' there. In my desktop environment (Ubuntu, 
Unity), the help frame stays in the background. If I explicitly switch 
to it (with `C-~') and press `q' in the Help window, the frame is buried 
again, but again, the focus returns to A.

Which mirrors the problem you've described in this report.

Maybe not deleting the frames is not the real problem, but them the 
problem is in some other window-related functionality.
