title: Propagate scroll event from parent container to a child container
body: <p>I'm going to split the page in 2 columns, sometimes the left column will have an overflow, and the right column will not. The right column would be the Parent, the left column is an overflow child. </p>

  <p>I set up a similar scenario here:
  <a href="http://jsfiddle.net/y1byh25d/1/" rel="nofollow noreferrer">http://jsfiddle.net/y1byh25d/1/</a></p>
  
  <p>Basically, i want to capture scroll events in the red area, and cause the green overflow container to scroll. It's a bit of weird one.</p>
