unsetting draggable

I have a widget that I set draggable with

    widget.getElement().setDraggable(Element.DRAGGABLE_TRUE);

and register a DragStartHandler. Later there comes a time when I want to unregister the handler, as well as disable dragging with 

    widget.getElement().setDraggable(Element.DRAGGABLE_FALSE);

However the widget is still draggable. When I look in Chrome Dev Tools, draggable="true" is still present. I've also tried

    widget.getElement().removeAttribute("dragable");

but draggable="true" is still present.

Is it not possible to remove draggable? I am using GWT 2.7.0 and running Chrome 54.
