Total list height (item-height*num-items) breaks at 37,282,700 pixels #103

When I create a list with 1M items, each 50px high, I cannot scroll all the way down (last item is #745,653) . Looks like chrome maxes out on div height - CSS shows list's container div height is 37,282,700px, and seems it cannot grow larger.
