    mode-controller: Special case activation by search provider
    
    When a search provider result is activated, the application goes
    directly to preview. Normally the transition to preview would have
    happened from one of the other views. This leaves the "old mode" in an
    undefined state. Special case the "old mode" to overview in this
    situation.
