It seems that you did not read the bug report well.  Did you see this
part?

 4. With `emacs -Q', you might not even notice the popped-up *Char Help*
    buffer, which means that it does not even do what the enhancer
    presumably intended.  It just flashes for an instant - impossible to
    read it, and serving no purpose but to annoy and puzzle.  This alone
    is a regression wrt previous Emacs releases.

Do I need to make the recipe clearer?

emacs -Q
M-x set-variable pop-up-frames t
In a writable buffer: C-q ?
