Use Event._attach to avoid creating unused facades There is a runtime execution and memory cost associated with creating event facades due to the pre-population of e.target, currentTarget, and relatedTarget that can be avoided in this case since it's filtering bubbled mouseover and mouseout events. Create the DOMEventFacade only after passing the filter criteria.
