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.
