[SVG, HTML-CSS output] menclose does not inherit color

Via the user group.

For SVG, it looks like we forget menclose in https://github.com/mathjax/MathJax/issues/1002. This seems to be it: https://github.com/mathjax/MathJax/blob/master/unpacked/jax/output/SVG/autoload/menclose.js#L116.

For HTML-CSS it seems to be https://github.com/mathjax/MathJax/blob/master/unpacked/jax/output/HTML-CSS/autoload/menclose.js#L58
