I've been going back through your earlier comments and found:

I doubt that this is the problem because

(let ((f (selected-frame)))
  (with-current-buffer (get-buffer-create "other")
    (make-frame))
  (select-frame-set-input-focus f)
  (with-current-buffer (window-buffer (minibuffer-window))
    (unwind-protect
        (progn
          (setq-local face-remapping-alist `((default :height 2.0)))
          (insert "hello")
          (read-key))
      (erase-buffer))))

doesn't resize the minibuffer either.  IIUC Markus was just lucky that
this worked earlier because then the frame title code resized the
minibuffer window.  After the fix of Bug#24285 it doesn't do that any
more.
