    menubutton: Propagate focus-on-click
    
    Propagate the focus-on-click setting to the button
    inside, so that setting menubuttons as !focus-on-click
    works as expected. This helps for menubuttons in
    header bars, where dragging on the button will otherwise
    steal focus from the content.
