Bad align and some char size - sans-serif font MJ 2.7

Created by: d3im

Hi,

in CHTML and HTML-CSS I have issue when I type e.g.: \(7,308 · 10^{–27}\) 7 and 1 is drawn with smaller font and 7 in exponent is aligned lower then 2. SVG seems OK.

I have this custom config:

MathJax.Hub.Config({
  menuSettings: {zoom: "Click"},
  "HTML-CSS": {
    availableFonts: ["TeX"],
    MMLorHTML: {prefer: "HTML"},
    imageFont: null,
    mtextFontInherit: true
  },
  CommonHTML: {
    mtextFontInherit: true
  },
  SVG: {
    mtextFontInherit: true
  },
  TeX: {
    equationNumbers: { autoNumber: "AMS" },
    extensions: ["mhchem.js"]
  }
});
MathJax.Hub.Register.StartupHook("CommonHTML Jax Ready",function () {
    var VARIANT = MathJax.OutputJax["CommonHTML"].FONTDATA.VARIANT;
    VARIANT["normal"].fonts.unshift("MathJax_SansSerif");
    VARIANT["bold"].fonts.unshift("MathJax_SansSerif-Bold");
    VARIANT["italic"].fonts.unshift("MathJax_SansSerif-Italic");
    VARIANT["-tex-mathit"].fonts.unshift("MathJax_SansSerif-Italic");
});
MathJax.Hub.Register.StartupHook("HTML-CSS Jax Ready",function () {
    var VARIANT = MathJax.OutputJax["HTML-CSS"].FONTDATA.VARIANT;
    VARIANT["normal"].fonts.unshift("MathJax_SansSerif");
    VARIANT["bold"].fonts.unshift("MathJax_SansSerif-bold");
    VARIANT["italic"].fonts.unshift("MathJax_SansSerif-italic");
    VARIANT["-tex-mathit"].fonts.unshift("MathJax_SansSerif-italic");
});
MathJax.Hub.Register.StartupHook("SVG Jax Ready",function () {
    var VARIANT = MathJax.OutputJax.SVG.FONTDATA.VARIANT;
    VARIANT["normal"].fonts.unshift("MathJax_SansSerif");
    VARIANT["bold"].fonts.unshift("MathJax_SansSerif-bold");
    VARIANT["italic"].fonts.unshift("MathJax_SansSerif-italic");
    VARIANT["-tex-mathit"].fonts.unshift("MathJax_SansSerif-italic");
});
MathJax.Hub.Register.StartupHook("TeX Jax Ready",function () {
    MathJax.InputJax.TeX.Definitions.number =
      /^(?:[0-9]+(?:\.[0-9]{3})*(?:,[0-9]*)*|,[0-9]+)/
});

MathJax.Ajax.loadComplete("[MathJax]/config/local/mathjax_sans_mhchem_cz.js");
