Title: Fixed - scrollbar exceeds container when scroll is not necessary

When the elements fit inside the container and scroll is not necessary, the scrollbar overflows the scrollbarContainer.
Cause: length is less than containerSize and this makes (containerSize/length) to be greater than 1. [for the equation in line 131 in this commit of mb-scrollbar.js]

Fixed it by setting the length to containerSize.
