I'm using a DataGridControl with a TableView. The row height can vary and sometimes rows can be taller than normal. This particular bug occurs if the total height of the row is higher than the next page would be.
What happens is that PageDn stops working and will not scroll to the next item. It appears to be rooted in TableViewItemsHost.HandlePageDownKey. It appears to be incorrectly calculating either the initialDesiredIndex or the focusContainerRealizedIndex and what's happening is these two values match and SetCurrent is never called.
Please let me know if you need me to put together a repro to demonstrate this.

It also appears that the issue repros in the sample program with Page Up. If you use Ctrl+End to scroll to the end of the DG then press Page Up note that it will not do anything.
