Error when scrolling memory editor

1. Stop at a breakpoint.
2. In Locals and Expressions view, right click on an object.
3. Select "Open Memory Editor" -> "Open Memory Editor at Object's Address" from the context menu.
4. Try to scroll to the very top of the editor using the scrollbar.
   You'll see an error message: "Cannot open : no file name specified"

Of course there is no file name because there is no file. This error should not happen. If it is not possible to scroll to the very beginning, then the scrollbar should not go further.
