    action-bar-start: Propagate primary button release events
    
    Previously, the release events for the primary mouse button on the
    navigation buttons were not propagated. Because of that, the GtkButton
    stayed in its pressed state.
    
    The middle button events will still be blocked as justified by the
    respective comment.
