multiline.js not found

[bcaso]

Description

I encountered a [Math Processing Error] while using \\, and in the console, I saw a message: Multiline.js Not Found.
I refer to this article https://discourse.jupyter.org/t/mathjax-alternate-renderer-issues-in-notebook-rendering/11089/3, download and extract the multiline.js in it, and move to /static/jax/output/HTML-CSS/autoload

bcaso@raspberrypi:~/.local/lib/python3.9/site-packages/jupyter_server_mathjax/static/jax/output/HTML-CSS/autoload $ ls
multiline.js

The \\ in the formula works again.
