Easily double-pressing Start or Back

Before Battle Mode was released, every time I pressed Start or Back on my controller, it would open up the appropriate GUI as expected. Ever since Battle Mode was released, though, it became very easy to simply press Start or Back, hear the noise it plays twice very quickly, and see no GUI. It still is possible to press it and see the GUI, but there's a good chance that the game will register a single press as two presses and cancel out the GUI. This occurs in both Battle Mode and regular worlds.
