DragAndDrop.StartDrag not worked on OSX

Hi, everyone.

I wrote an editor script to create a EditorWindow. It’s use for manager some asset.

I call DragAndDrop.StartDrag() to start a drag&drop in this EditorWindow. Another EditorWindow can get DragPerform event to finish the drag&drop. It works very well on windows.

On the Mac, you can see the drag title, but can’t get any DragXXXXX event.
But if you drag a asset from project view to the EditorWindows, it works.

the code like this:

void OnGUI()
{
    if (Event.current.type == Event.mouseDrag)
    {
        DragAndDrop.PrepareStartDrag();
        DragAndDrop.StartDrag("DragComponent");
        DragAndDrop.objectReferences = Selection.objects;
    }
}

window2:

void OnGUI()
{
    DragAndDrop.AcceptDrag();
    if (Event.current.type == Event.DragUpdated )
    {
         DragAndDrop.visualMode = DragAndDropVisualMode.Link;
         //dosomething
    }

    if (Event.current.type == Event.DragPerform )
    {
         //dosomething
    }
}

Is there something wrong with my code? Or it is a bug?
Does anyone know about this?
