There are a few valid reasons to bind to scroll events, such as zooming in a map.  However, almost every time this happens, it is by ACCIDENT and is NOT what I wanted to do.  I would gladly lose the ability to zoom a map, or scroll a div with sexed up widgets with the wheel if it meant that I could actually scroll the page without having to be ridiculously careful about where I put the mouse cursor.

A better solution perhaps would be to implement some sort of timeout.  Only send the scroll events to a div after it has had focus for greater than X ms, or when the page is not currently scrolling.

Reproducible: Always

Steps to Reproduce:
1.  Load the example page
2.  Scroll the page
3.  Curse like hell when the page stops scrolling and the map zooms out to galaxy level because the cursor happened to be over the embedded map
Actual Results:  
The page stopped scrolling and the map zoomed out to galaxy level because the cursor happened to be over the embedded map

Expected Results:  
The page should have continued scrolling.
