Evaluate these sexps:

(setq special-display-regexps '("[ ]?[*][^*]+[*]"))

(setq special-display-frame-alist
      '((foreground-color . "Black")
        (background-color . "LightSteelBlue")))

(setq pop-up-frames t)

(defun special-display-popup-frame (buffer &optional args)
  "Display BUFFER in its own frame, reusing an existing window if any.
Return the window chosen.  Window is not selected within its frame.

If a new frame is needed, then `make-frame' is called to create it,
with BUFFER as the current buffer.

If ARGS is an alist, use it as a list of frame parameter specs.
If ARGS is a list whose car is a symbol, use (car ARGS) as a function
to do the work.  Pass it BUFFER as first arg, and (cdr ARGS) as the
rest of its args."
  (if (and args (symbolp (car args)))
      (let* ((window (apply (car args) buffer (cdr args)))
             (frame (window-frame window)))
        (when (fboundp 'fit-frame) (fit-frame (window-frame window)))
        (raise-frame frame)
        window)                         ; Return the window.

       ;; Reuse the current window if the user requested it.
       (when (cdr (assq 'same-window args))
         (condition-case nil
             (progn (switch-to-buffer buffer) (selected-window))

         (when (and (fboundp 'fit-frame)

         (frame-selected-window frame)))))) ; Return the window.

Try C-h f setq - no problem. The frame background is LightSteelBlue.

Try M-x list-faces-display. The frame background, or at least the
background of buffer *Faces*, is white. The frame background appears
to be LightSteelBlue, which is correct, but that only shows in the
fringe and the minibuffer. (So, for a frame without minibuffer and
fringe, no LightSteelBlue background is seen.

`list-faces-display' should not impose a special background for its
window/buffer. (And how does it do that, anyway?)
