Issue while click and drag on Frozen column footer scroll area.

[viveks-m]

At the bottom right intersecting area of vertical and horizontal scroll bar area, when clicked and dragged by the user, it breaks the frozen column and the grid. Either the user has to replicate the action dragging back the opposite direction to bring back or refresh the page is the only option.
