    st/theme-node-drawing: Fix inner shadow fast path condition
    
    We want to use the fast path of filling the entire area if either the
    left and right shadows would overlap or the top and bottom shadows. The
    latter check was wrong due to a typo resulting in the regular path
    being used in some cases it couldn't (and shouldn't) handle.
    
    This was causing the inset shadow used to highlight panel buttons to
    not appear for buttons above a certain width.
