Have you ever tried that workaround?

I now attach a patch that should address this problem with the help of
an additional argument PERSISTENT for 'set-window-scroll-bars' and
'set-window-fringes'.  If set, the requested settings should survive
subsequent invocations of 'set-window-buffer' for the window (in
particular the minibuffer window) in question.  If you build Emacs
yourself, please try it.

Thanks, martin
