Nick, I have no opinion on whether or not mouseenter/mouseleave should be rolled into core, but if they are I think they should be implemented as custom events, just like we implemented dom:loaded. I'm highly reluctant to give the former a special treatment that we didn't give the latter. As we discussed on GitHub, the solution is to enhance Element#fire so that one can tell a custom event not to bubble. In most browsers this is easy. In IE, as you noted, the fireEvent method gives no control over bubbling behavior. But IE also implements a bunch of proprietary events that nobody ever uses, and some of these are *by their nature* non-bubbling. For instance, there's "onpropertychange," which is IE-only and not part of any standard [1]. Just like we borrow "ondataavailable" for custom events, so can we borrow "onpropertychange" to get non-bubbling custom events. Some quick code confirms this works. I've set this as a to-do for 1.6.1. Fun fact: originally I'd wanted to use the "onbounce" event [2], which is one of three different events that IE reserves for MARQUEE elements. It does not bubble, but is cancelable, so it would've been _perfect_. Sadly, IE throws an error when you try to trigger an "onbounce" event on a non-MARQUEE element. I promise I'm not making this up.
