[textmacros] \tag{$*$} spacing issue

[pkra]

E.g.$$\text{Tag with math}\tag{$*$}$$ will render differently (using SVG but see below).

Without textmacros extension:

With textmacros extension:

I think this come down to a missing data-mjx-texclass="ORD" when the extension is active.

You are correct about the cause. It should to be hard to fix. Thanks for the report!

PS, you could use \tag{${*}$} for now to work around the problem.

I've made a PR to address the issue. But in the meantime, you can use

MathJax = {
  loader: {load: ['[tex]/textmacros']},
  tex: {packages: {'[+]': ['textmacros']}},
  startup: {
    ready() {
      const TextParser = MathJax._.input.tex.textmacros.TextParser.TextParser;
      const TextParser.prototype._PushMath = TextParser.prototype.PushMath;
      TextParser.prototype.PushMath = (mml) => {
        if (!mml.isKind('TeXAtom')) {
          mml = this.create('node', 'TeXAtom', [mml]);  // make sure the math is class ORD
        }
        this._PushMath(mml);
      };
      MathJax.startup.defaultReady();
    }
  }
}

as part of your configuration in order to get the effect of the patch.
