`System.Runtime.InteropServices.ComTypes.IDataObject` vs `Windows.Win32.System.Com.IDataObject`

Is your feature request related to a problem? Please describe.
Hello guys.
I'm having issue with implementing Drag&Drop in WPF for .NET 9, using IDropTargetHelper.
The problem is with DragEnter event handler.

public partial class MyWindow {
...
  Windows.Win32.UI.Shell.IDropTargetHelper _dropTargetHelper = Activator.CreateInstance(Type.GetTypeFromCLSID(PInvoke.CLSID_DragDropHelper)!) as Windows.Win32.UI.Shell.IDropTargetHelper;
...

  private void MainWindow_DragEnter(object sender, DragEventArgs e)
  {
    ...
    var pointWpf = e.GetPosition(this);
    var point = new System.Drawing.Point(Convert.ToInt32(pointWpf.X), Convert.ToInt32(pointWpf.Y));
    _dropTargetHelper?.DragEnter(HWnd,

    //here's the issue, it always results into null:
    e.Data as Windows.Win32.System.Com.IDataObject,

    in point, (Windows.Win32.System.Ole.DROPEFFECT)e.Effects);
}
...

Here, e.Data implements interface System.Runtime.InteropServices.ComTypes.IDataObject while Windows.Win32.UI.Shell.IDropTargetHelper expects it's own Windows.Win32.System.Com.IDataObject.
And even thought these both IDataObject are the same, there's no way to cast them, as .NET-wise, they are completely different interfaces.
And for PInvoke, CsWin32 does use System.Runtime.InteropServices.ComTypes.IDataObject.
For example, when adding SHCreateShellItemArrayFromDataObject to NativeMethods.txt, PInvoke.SHCreateShellItemArrayFromDataObject expects System.Runtime.InteropServices.ComTypes.IDataObject.
Therefore, it looks like the issue is scoped to COM interop only.

Describe the solution you'd like
When generating something that uses IDataObject, use System.Runtime.InteropServices.ComTypes.IDataObject instead.
Or provide a way to configure mapping in NativeMethods.txt, something like

CLSID_DragDropHelper
IDropTargetHelper
IDataObject=System.Runtime.InteropServices.ComTypes.IDataObject

Describe alternatives you've considered
Don't use CsWin32 in favor of plain, manually crafted COM interop.
Things like Marshal.QueryInterface/Marshal.GetComInterfaceForObject/Marshal.GetObjectForIUnknown or Unsafe.As didn't work.
