DefaultRenderHandlerStartDragging Method  | 
Version 93.1.111 
            Called when the user starts dragging content in the web view. Contextual information about the dragged content is
            supplied by dragData. OS APIs that run a system message loop may be used within the StartDragging call.
            Don't call any of the IBrowserHost.DragSource*Ended* methods after returning false.
            Return true to handle the drag operation. Call 
DragSourceEndedAt(Int32, Int32, DragOperationsMask) and 
DragSourceSystemDragEnded either synchronously or asynchronously to inform
            the web view that the drag operation has ended.
