Can't you just return false from an event handler to prevent further
bubbling?

Mouseover/out events will trigger when elements contained inside
the EventTarget are hovered, and then bubble up. This is contrary
to the most obvious interpretation, as you are still inside (over)
the targeted element. IE supports two events, mouseenter[1] and
mouseleave[2], which solve this problem by not bubbling.
It is possible to work around the problem by using target/
relatedTarget and walking up the DOM tree. However, this requires
extra code for every event handler. Besides, these events were
often not meant to be generated in the first place, by the intent
of the author.
I have no statistics for how often mouseover/out are used with and
without intent of bubbling, but the anecdotal evidence from my own
experience has never found me wanting it.
I suggest these two events be added to the web applications spec.
