Summary: NavigationBar should coalesce consecutive dividers when items are hidden. Currently this is only done when items are forced hidden when collapsing the bar to fit the available space. We should always coalesce dividers during a layout, since hiding items (NavigationItem.prototype.hidden) can also cause dividers to pile up.
