    system: Align submenu labels with parent - adjust for deeper hierarchies
    
    Adjust the previous commit which applied the alignment to :first-child
    descendants, instead of only immediate children. This fixes alignment
    issues for a number of Shell extensions by making it easier to override
    with a .popup-menu-item style-subclass.
