dragged item does not follow mouse when css zoom is not 1

[topvis]

To reproduce this issue, on this example page, set zoom: 1.2 of any div that contains vue-dndrop component and then drag an item. The dragged item will be off the mouse position as shown in the screenshot below. I was dragging "Draggable 1-2". The mouse cursor is where the red arrow is pointing and the item "Draggable 1-2" is not following the mouse.
