Unless it appears on another frame. If with emacs -Q you do
(let ((pop-up-frames t))
(display-buffer (get-buffer-create "baz")))
that buffer is shown on a new frame and its window is selected.

Maybe we should provide an alist entry like select-frame for this. If
the buffer already appears in another frame, we would select the frame
only if the entry is set. If a new frame is created, we could try to
not select it if the entry is not set and the window manager supports
creating a frame and not selecting it.
