    gtk-style: Apply proper border to boxes-menu-row
    
    The "Enter URL" button in the New Box wizard had a border-radius
    applied to its bottom instead of the top.
    
    The intention of this styling is to indicate a correlation between
    the button and the content below. This way, the border-radius
    should be applied in the top as the mockups indicate.
