Can someone explain this comment to me?  I see it in a number of  
places, and it worries me.  I'm concerned that we are using the  
"assign event handler as property" interface, because of the  
possibility that more than one place in the code will try to assign to  
the same event and end up losing.  I thought attaching event handlers  
supported both cancelling bubbling and default suppression, so I don't  
understand the comment.

Please enlighten me.
