If change "resizable" and "dragable" properties of gridconfig, CSS "cursor" property of grid elements in DOM remains with random values (ew-resize, move, ...)

I have a set of items in my angular2-grid container. I need to dynamically enable and disable resize and drag mode (edit mode). When I disable edit mode (set resizable and draggable to false) DOM contains random values of css "cursor" property in grid elements.
