Pagination footer Conflicts with Cell nav. Hides focused cell

When you have page navigation and cell nav enabled and you use keyboard nav to navigate to the bottom of the grid the focused cell falls below the bottom of the grid.

Additionally, you can't see the last item in the list without scrolling.

To reproduce:

1. Click on a cell inside the grid.
2. Use the arrow keys to navigate to the bottom.
3. Watch focused cell disappear behind the page nav footer.
