AngularJS analogue to jQuery preventDefault for keydown?

I need the browser to respond to keydown arrow events in focused scrollable boxes. Here is a Plunker to show what I mean

Even if I tell the event to stop propagating with event.stopPropagation() and make the event handler return false the box keeps scrolling on keydown.

Unless I'm mistaken as far as what you're looking for, you should just be able to change your

event.stopPropagation()

back to

event.preventDefault()

and it will work as desired.
