    combo-box-menu-item: Propagate style changes to the combo menu
    
    ComboBoxMenuItems use ClutterClones to reconstruct the active item
    in the associated ComboMenu to not impose a particular MenuItem type
    in the menu. However, this results in style changes (for instance
    those triggered by icon-theme or text-scaling-factor changes) of
    the ComboBoxMenuItem not having a visual effect until the ComboBoxMenu
    is shown.
    As a fix, force a style update on the ComboBoxMenu when the item's
    style changes.
