FastScroller touch input doesn't respect RecyclerView padding

[alexandermarinissen]

I have a RecyclerView that matches the width and height of my display. However, the RecyclerView has a top and bottom padding of let's say 100dp. The FastScroller is rendered correctly (i.e. it only starts 100dp from the top of the screen and ends at 100dp above the bottom), but it still thinks touch input should go from the very top of the screen to the very bottom. This means that I have to drag my finger all the way to the top, instead of 100dp from the top, and thus the FastScroller doesn't track my finger accurately.
