Table in DDAbsoluteLayout dd fails partially when Table has DropHandler for its rows

[johannest]

Add table with DropHandler (see below) in the DDAbsoluteLayout and try to drag and drop it a short distance down from its header within the area that the Table originally fills: after drop the Table returns to original place. The reason is probably that Table thinks that you are trying to drag and drop its rows even though you dragged from its header.

final Table t = new Table();
        t.setWidth("300px");
        t.setHeight("300px");
        t.addContainerProperty("test", String.class, null);
        t.addContainerProperty("asdas", String.class, null);
        t.addItem(new String[]{"sss","ssssss"}, "asdasdsa");

        t.setDragMode(TableDragMode.ROW);
        t.setDropHandler(new DropHandler() {

            @Override
            public AcceptCriterion getAcceptCriterion() {
                return AcceptItem.ALL;
            }

            @Override
            public void drop(DragAndDropEvent dropEvent) {

            }
        });
