    status/volume: Request symbolic style for device menu items
    
    We get device icons from gnome-volume-control, which itself may
    get them from pulseaudio. That is, we don't have control over
    whether icon names are symbolic.
    
    As we do want menu items to use symbolic icons, enforce that
    via CSS instead.
