There seems to be a problem when the table is scrolled to its end by pressing the End key.
What happens is that instead of displaying the last rows of the table, a blank space is displayed instead. It is rather tricky, though, because it does not occur on every case.

In the sample provided in the link above, do the following to reproduce the issue.
1.) Order the table by Last name in ascending order (click table header once).
2.) Click anywhere on the table aside from the headers (e.g. first row).
3.) Press the "End" key.
