    slot: ensure we're back from an active search when changing location
    
    We used to keep track of the search active state using the state of the
    search toggle button; unfortunately, the button is per-window,
    so its active state will also be synchronized when switching tabs.
    This will cause a non-search slot that becomes active following a tab
    switch from a search slot to think its search just became inactive, and
    will then change its location to the default ($HOME).
    
    Fix the bug by keeping an additional state per-slot for whether there's
    an active search.
