dropModel->drop prevents dropping of nodes

[Autoflow]

Hi.

Just noticed within your examples that setting a drop callback on dropModel prevents nodes from beeing moved:

$("#dndgrid").pqGrid({
            height: 500,
            autoRow: true,
            dataModel: dataModel,
            complete: function () {
                this.flex();
            },
            dragModel:{
                on: true,
                diHelper:['OrderID']
            },
            dropModel:{
                on: true,
      drop: function(evt, ui) { alert('node(s) won'n not moved with me ..'); return true; }
            },
            //pageModel: { type: 'local', rPP: 20, rPPOptions: [1, 10, 20, 30, 40, 50, 100] },
            colModel: columns,                       
            title: "Shipping Orders"           
        });       

Is this a bug ?

drop callback is used to implement custom logic of move rows.

it's used in this example of drag and drop between grid and other component: https://paramquery.com/pro/demos/dnd_other
