I have following problem which also shows in Telerik Example for Virtual Grid ("First look").
Steps to reproduce.
1) I have a greed which has both vertical and horizontal scroll bars.
2) Scroll to the very bottom of the grid
3) Select the last row
4) Scroll all the way to the right
At this moment the selected row disappears from the view, and 4th from the bottom row is moved to the bottom of the grid.
We are currently using Win_2017_3_912 version.
