Can't cancel dragging after it started

[goliney]

I find it impossible to cancel the dragging event. If you change your mind while still holding the mouse button pressed, you can't go back. The item will be dropped anyway.

I tried ESC button, or dragging the item away from the tree container. But the onMove is still fired.

Expected result:

onMove is not fired if ESC is pressed during the drag or if the item is dropped outside the tree area.
