If your mouse-wheel repeat is very frequent (>= 60Hz) or your machine is slow enough that you can receive more than one mouse-wheel event before the associated animation callback for smooth scrolling, the page will jump to 0,0. I have a one-line fix for this, but seeing if I can write a test to go with it.
