Bug report

When sorting is enabled for a virtualized Grid with local data, in some cases the Grid does not show correct items when sorted.

Reproduction of the problem

1, Open the Dojo example
2. Scroll to the bottom
3. Sort the Grid

Current behavior

Only the last 3 items are displayed. (screencast)

Note: The issue does not occur every time.

Expected/desired behavior

Enough items to fill the Grid height should be displayed. There should be no blank space without records.
