Description
When a drag is in progress and the user drags the mouse cursor to the top or bottom of the Grid, the grid should start to automatically scroll.
actually nothing happens.
if I have a grid with 100 rows, of which I only see let's say 20, I can't drag the first row to the end of the grid with one single drag and drop movement

Research direction
Start by reproducing the issue with a grid containing 100 rows while viewing only about 20, then inspect the row-drag behavior in the Vaadin framework code. The work is done when dragging a row to the top or bottom automatically scrolls the grid so the row can be moved to an off-screen position in one drag.
