Please persist macros with KaTeX globalGroup about mdmath HOT 2 OPEN

This is already doable. In settings.json:

    "mdmath.katexoptions": {
        "globalGroup": true,
    },

from mdmath.

I added

    "mdmath.katexoptions": {
        "globalGroup": true,
    },
    "markdown.math.enabled": false,

to my settings.json and reloaded vscode, but markdown still does not display the rightarrow correctly:

$\newcommand{\ra}{\rightarrow}$

$\ra$

Edit: If I also add "markdown.extension.math.enabled": false to settings.json, then the $\ra$ displays correctly. However

1. If I re-render the preview the $\newcommand{\ra}{\rightarrow}$ displays in red as invalid latex, I believe because the command still exists from the previous rendering
2. I still get an error when using these commands in a python notebook: ParseError: KaTeX parse error: Undefined control sequence: \ra at position 1: \ra.

This may be related to this katex issue.

Environment

- OS: Ubuntu 20.04.4 LTS
- mdmath v2.7.4
- VSCode 1.64.2 (with the native `Markdown > Math` setting disabled)

from mdmath.
