[Gradebook] Vertical scrolling with arrow keys should end in column

Problem statement:

When I use the arrow keys to navigate up and down through the gradebook it will wrap to the next column when I get to the bottom. In classes where there are more students that fit on the screen this makes it very difficult to scroll to the students at the end of the alphabet to make adjustments to their grade. I often end up past them and into the next column, necessitating scrolling to their name again. It would be more convenient if it just stopped at the bottom box instead like it does if you scroll all the way to the top.
