While dragging a widget using gesture.Drag, which is also listening to
gesture.Hover events, the Hover handler loses out to the Drag handler
and receives a pointer.Cancel, but "func (h *Hover) Hovered(q
event.Queue) bool" continues to return true.

Unless I am using this incorrectly, in which case please educate me, I
believe that the pointer.Cancel event should be considered to have a
similar effect as that of pointer.Leave making  "func (h *Hover)
Hovered(q event.Queue) bool" return false.

See reproducer code below along with a screencast.

You're absolutely correct. All gesture handlers, gesture.Hover included,
should handle pointer.Cancel. Please file an issue, or send us a patch
that fixes the problem.
