[whatwg] Is there a way to stop scrolling when pressing directional arrows?

[Carlos Andrés Solís]

Hello! I've been noticing a problem in many HTML5 test apps, very especially
games. When the directional arrow buttons are pressed, the screen scrolls.
This is a problem that, as far as I know, Flash had solved by changing the
focus of the application to the app. Is this doable in HTML5?
