this fixes moving away from the scroller if the content is not from elm.
What happens if this is not regular, is that the movement logic picks up
the scroller as the only focused element, which is right, since the
scroller is focused (via some wrapper object). However, the scroller in
the object is only logical (which is used for containers that never get
focus), but this is not right in this regard, as focus moves to the
scroller, in this configuration.
