Alas, this is no longer true.  Start Emacs 29 via

emacs -Q --eval "(setq default-frame-alist '((minibuffer . nil)))"

Now type C-x 5 o to switch to the normal, minibuffer-less frame and then
type C-x f.  Next try to access the normal frame via C-x o, C-x 5 o, the
window manager's Alt-TAB or any other key combination.  This used to
work ever since.  Now you are in a modal dialogue exactly as described
above.
