Well, to be honest, I've been focusing on Firefox and Opera mainly when
developing software and never even thought that order is not guaranteed,
before the task to support IE arrived! So there is plenty of code to
refactor, which is very frustrating. I know that relying on event order
isn't a best practice, but such a convinent one. jQuery guys would
understand me, because their events are always executing in defined order.
