It’s not that it was required, but it was a pain in the butt figuring out how to arrange the event handlers on the different elements so that you don’t end up with a situation where you get a flickering bubble because you hide the bubble, and that fires a mouseover event that, in turn, displays the bubble again. That fires a mouseout event that causes the bubble to be hidden.
