Evaluating with emacs -Q

(add-to-list 'special-display-buffer-names '("*Completions*" foo))
(setq w32-grab-focus-on-raise  nil)

(defun foo (buffer &optional args)
  (interactive)
  (let* ((mini-win  (active-minibuffer-window))
	 (mini-frame (window-frame mini-win))
	 (window
	  (select-window
	   (funcall special-display-function buffer args)))
	 (frame (window-frame window)))
    (raise-frame frame)
    (redirect-frame-focus frame mini-frame)
    window))

and typing

C-h f set- TAB

gets me a new frame with input focus.  Evaluating with emacs -Q

	 (frame (window-frame window)))
    (raise-frame frame)
    (redirect-frame-focus frame mini-frame)
    window))

and typing

C-h f set- TAB

gets me a new frame with input focus in the old frame.

Verified with Emacs 25 and 26 under Debian GTK+ and Windows XP.
