I don't, and I think we should apply the patch you are proposing.  Currently scroll events are handled similar to motion/enter notify events, which means that when scrolling (for example) a tree view with scroll events, a tooltip continues to be visible.  I agree with you that this behavior does not seem to make much sense.

Any objections to this change?
