       .rst-content wrapper regular pages get. theme.css only assigns
       FontAwesome to the h1 permalink icon when scoped to
       ".rst-content h1 .headerlink", so here the icon's pilcrow
       character falls back to the body font (no matching glyph, hence
       the square) instead of rendering as the link icon. Mirror that
