mdVirtualRepeat: Buggy scrolling near end of list

[aviraldg]

Demo: http://codepen.io/aviraldg/pen/JYyBEL

Try to scroll to the bottom of the list.

Expected: Scrolling stops at end of list.

Actual:

1. Scroll position "jumps" jarringly when near end of list, translateY keeps increasing (despite no actual increase in scroll position)
2. After step 1, scrolling up is also useless and exhibits the same buggy behaviour (apparently until translateY returns to an appropriate value)

Same thing happening on my end:
