    Support setting the image after construction
    
    This patch allows the icon in PopupImageMenuItems to be changed at
    any time, while preserving the item and all other properties (style,
    signals) attached and without rebuilding the whole menu. This is useful
    for images reflecting a dynamic status (e.g. cellular strength
    indicator or battery level)
