    appDisplay: Don't use symbolic icon at full size for system actions
    
    When attempting to account for scaling in e65e5ede the icon_size of the
    StIcon was set to the target size, overriding the icon-size set in the
    'system-action-icon' CSS, which was only half the size. The intent of
    that commit however was not to scale up the symbolic icon, but the
    circle around it. Do this by manually applying the scaling factor.
