Tooltip frame is hidden as soon as mouse moves. I wish to suspend that
behaviour while a timer is active; must be some mouse motion event; I am
not sure where to look for it; where is it defined.

Yes. I think it can be hacked in x-show-tip: will have to check if a
sticky tooltip is enabled. I can save it as buffer local variable in the
buffer, so it could be read in x-show-tip which then can either
delete/re-use frame or create a new frame.
