Pause/Break as a Keyboard ShortCut (Win32, *Possibly* Delphi-specific)

Question

Is it not possible to use the Pause/Break key in keyboard shortcuts?

I know I can respond to the Pause/Break key, e.g.

procedure TForm1.FormKeyDown(Sender: TObject; var Key: Word;
  Shift: TShiftState);
begin
  if Key = VK_PAUSE then
    ShowMessage('VK_PAUSE pressed');
end;

However, I am unable to respond to the Pause/Break key using the TShortCut properties, e.g. in menu items and action lists. The Object Inspector lets me enter PAUSE, Shift+PAUSE, Ctrl+PAUSE, Alt+PAUSE, Shift+Ctrl+PAUSE etc. so it clearly recognizes the PAUSE key. But when I run the application, the menu item/action is not triggered on the specified shortcut. Is there a known workaround?
