@pkra, I'm not sure what you have in mind for the internal MathML. Are you suggesting extending the `columnlines`, `rowlines`, and `frame` attributes to include `double` as well as `solid`?...

The double vertical lines now work in v4.0, but not the double horizontal ones. I'll have to look into adding those.

Thanks for the report. I'm looking into it. For now, you can work around it by using ``` latex \DeclareMathOperator*{\argmax}{{arg\,max}} \DeclareMathOperator*{\argmin}{{arg\,min}} ``` using an extra set of braces.

No. I'm wrong the braces don't help. I was sure it was working a few minutes ago, but now it isn't working. I must have not been testing it correctly....

I have figured out the issue and will make a PR to fix the problem. It is actually two related issues, one where the TeX class of the operator isn't...

In response to #3322, MathJax v4 remapped `\perp` from the incorrect character U+22A5 (UP TACK) to the correct U+27C2 (PERPENDICULAR). The TeX class for `\perp` was being assigned automatically from...

In the meantime, you can incorporate ``` js MathJax = { startup: { ready() { const {OPTABLE, MO} = MathJax._.core.MmlTree.OperatorDictionary; OPTABLE.infix['\u27C2'] = MO.REL; MathJax.startup.defaultReady(); } }, }; ``` into your...

MathJax's internal format is MathML, and there is no natural way to represent `\intertext` or `\shortintertext` in MathML. So it would be difficult to support these macros. Indeed, I can...
