Its a bit more subtle than that. GUD tooltips use track-mouse (ordinary
tooltips work at a lower level and don't rely on events in lisp). For a GUD
tooltip to work, the lisp-level mouse-movement event must be generated in the
buffer with the overlay arrow and the mode of the selected buffer must belong
to tooltip-gud-modes. Note that the mouse-movement need not occur in the
selected buffer. The list `tooltip-gud-modes' includes gud-mode so that the
user may move the mouse over a variable in the buffer of the source while the
GUD buffer remains selected.
Why was it made to depend on the selected buffer? Why implement such
bizarre behavior? I think that counts as a bug; can we fix it?
If it is so hard to document, it will strike the user as a bug.

Maybe it is a bug but no-one has complained about it, probably because not
many people use GUD tooltips. The comments in tooltip.el suggest that this is
a kludge to avoid display problems (Gerd Moellmann?), so I'm not sure that
there is an easy fix. There are other problems that I would like to fix such
as the fact that if GUD tooltips display in the echo area then so must
ordinary tooltips, but these are not showstoppers. Surely solving these
problems should wait till after the release?

This is a bug fix; in principle, there is no reason to delay it.
If it would require fundamental changes, then we don't want to
install them now. If it can be done in a localized way,
then it need not wait.
