    highlight: reload highlight engine after diagnosing
    
    While it isn't guaranteed that diagnose data will be used for highlighting,
    it's likely at the moment (and a convenient place to do this the first
    time).
    
    Highlighters can adapt to changes via something else in the future. But
    this seems KISS for now.
