This is either

(3) Give tooltip frames a minibuffer window of some other frame (with
    the usual consequences when trying to delete that frame).

or

(4) Try to find a frame with a minibuffer and put the message there
    (it might be tricky to find the most suited minibuffer here).

The obvious candidate here is the minibuffer window of tip_last_frame
(making sure the tooltip frame gets deleted when tip_last_frame is
deleted).

The changes required to implement that are just as substantial as
those for not showing messages.
