[Menu] is not scrolled, when navigated via keyboard

Open the "File" menu, and it is supposed, that you have menu, which contains too many items, to fit on the screen.

Move mouse over one of the items, and press "down" button and keep it pressed. I see rotative navigation, but I don't see scrolling in the menu.
