Expected Behavior

The Grid scrolling position should be preserved.

Additional Considerations

When sorting is applied, the values in cells are changed making cells with shorter widths get bigger (or the opposite) and hence changing the horizontal scroll. In this scenario, the new scroll position that should reflect the previous one might be unknown since the cell can contain different values in length which will change the horizontal scroll dimensions. In this case, resetting the width to its initial position could also be considered.
