Bug: scroller moves far from current position on some cases

[AndroidDeveloperLB]

steps:

1. make the items count to 20.
2. drag the fast-scroller to the middle (or anything else).
3. scroll a really tiny bit (in the recyclerView itself)

The bug: it shows the scrollber very far from its previous position.

@AndroidDeveloperLB, I've reproduced this behavior, I think it's because the real linked position is lower so, scrolling the RV it adjust the handle at the correct (for him) Y height.

I can see a solution, when finish to drag the FastScroller, we can recalculate the real position, at that point, the handle will be positioned at the right position.

@davideas It would be great if you'd show a solution .
