Propagation ("bubbling") is very handy, and essential for delegated handlers. But there are times when you catch an event at some element and because of the way you are handling it, you don't want any handlers attached to parent elements to also fire.

So the reason you would use this would depend on the way you have attached handlers, and what the handler code is doing.
