[Grid] Row dragging not working as expected

[MarielaTihova]

Go to this example https://staging.infragistics.com/react-demos/grids/grid/row-reorder and observe the behavior.

For fixing:

Expected result:
Regardless of which row we drag, it should be placed wherever we drop it.
Actual result: When we drag and drop a row it is being placed where we drop it only sometimes. The bug is being easily reproduced, but I can't fixate on the exact cases in which the feature doesn't work. Needs further investigation.

• The same works as expected in Angular!

For improvement:

Add a visual identifier of where the dragged row will be placed.
