Now floating headers get 2 interpolators: one for the header content itselt, and one for the all apps content that follows. That way, they can choose to intperolate part of their content as if it were part of all apps instead of the header. Currently, we do this to animate predicted icons quickly, followed by the all apps icons, predictions text, all apps scrollbar, and all apps divider as you continue swiping.
