[Bug 728643] [NEW] Kinetic scrolling implementation continues to send scroll event after physical action has stopped

 

Public bug reported:

On natty with the multi-touch track pad on my macbook pro, when I do a fast scroll on a tab, and then hit ctrl+w while the kinetic scroll is still in progress, the system interprets this as ctrl+scroll and zooms into my page, and then closes the tab.
