[MacOS] Unable to see Drag animations for an NSTextView

Hi,

I'm trying to drag an NSTextView from one NSView to another. I'm getting the right events, but the drag animation is not coming up.

Subclassed TextView:

class MyTextView:NSTextView, NSPasteboardItemDataProvider
{
    func pasteboard(_ pasteboard: NSPasteboard?, item: NSPasteboardItem,    provideDataForType type: NSPasteboard.PasteboardType)
    {
        
        NSLog ("Paste")
    }
    
    override func mouseDown(with theEvent: NSEvent) 
    {
       
      
      let pasteboardItem = NSPasteboardItem()
      pasteboardItem.setDataProvider(self, forTypes: [.string])
      
      
      let draggingItem = NSDraggingItem(pasteboardWriter: pasteboardItem)
      draggingItem.setDraggingFrame(self.bounds, contents:.Publisher)
      
      
      beginDraggingSession(with: [draggingItem], event: theEvent, source: self)
    }
    
    override func draggingUpdated(_ sender: NSDraggingInfo) -> NSDragOperation 
    {
        return NSDragOperation.copy
    }
}

Subclassed NSView to receive the drop event:

class DropView:NSView
{
    func EnableDrop ()
    {
        // Registering for drag drop types

        registerForDraggedTypes([NSPasteboard.PasteboardType.string, NSPasteboard.PasteboardType.URL, NSPasteboard.PasteboardType.multipleTextSelection, NSPasteboard.PasteboardType.color])
    }

    func shouldAllowDrag(_ draggingInfo: NSDraggingInfo) -> Bool 
    {
        
      return true
      
    }

    override func draggingEntered(_ sender: NSDraggingInfo) -> NSDragOperation {

        // To show a copy tooltip during drop

        return NSDragOperation.copy
    }

    override func prepareForDragOperation(_ sender: NSDraggingInfo) -> Bool 
    {
        
      return true
    }

    override func performDragOperation(_ draggingInfo: NSDraggingInfo) -> Bool {
        
        let draggedview = draggingInfo.draggingSource as! NSView
        
        NSLog ("Drop received")
        
        return true
    }
}

When I create my view in the ViewController, I do "myviewobj.EnableDrop()" to receive drop events. However as stated above, I'm not able to see the drag animation happening, however, I do get events for it.
