Update dnfdragora_runs for over-large window on KDE
    
    The dnfdragora window is too big on current KDE so we can't see
    the top of it (where we used to match). It's kinda better to
    match on some active element of the app than just the window
    title anyway (so we don't 'pass' if the window loads but is
    empty, or something like that).
