fix(card): in the browser's detail view the list follows the card shown

Browse source 
Next and Previous changed the card beside the list, but the list stayed
where it was, so the card shown soon lay outside it. The list now
scrolls the card's tile into view: at its end going down, at its start
going up, and near it first where the tile lies too far to be built.
