216841 - Create DOM events at the start of event dispatch

Status: NEW

(Core :: DOM: Events, defect, P5)

Description

[Brian Ryner (not reading)]

Currently, DOM events are created lazily by HandleDOMEvent() implementations. 
Creating a DOM event is cheap (this optimization is very premature), and dealing
with the fact that the DOM event may not have been created yet makes some code
(nsGenericElement::HandleDOMEvent, nsXULElement::HandleDOMEvent,
nsEventListenerManager::HandleEvent) more complicated than it should be.

This is a dup of bug 198657, not that it matters.  Keep whichever one open you want.
