    gtk/main: Reset active state on grab broken only if implicit
    
    An implicit grab means some button is down, reset the active state
    only in that case when we get a grab broken event.
    
    Avoids active state accounting warnings when we do get active grabs
    broken (e.g. after selecting a menu option).
