It is not possible to mark more than one identical footnote.

[bulhakovolexii]

I found the following problem.

With a clean installation and configuration according to the documentation and the latex module is enabled...

const withNextra = require("nextra")({
  theme: "nextra-theme-docs",
  themeConfig: "./theme.config.jsx",
  latex: true,
});

module.exports = withNextra();

...if i mark a footnote to the same reference more than once, compiling is impossible.

But if there is no more than one footnote, or the latex module is disabled, then everything is fine.

The problem also does not occur if i change the file extension from .mdx to .md.

Please help me fix this problem. :heart:

after more deep dive into this problem, I figured out that updating @mdx-js/mdx from 2.3.0 to 3.0.0 fixes this issue (Nextra 3 already uses mdx v3)

Use Nextra 3 alpha and refactor $$ style to https://the-guild.dev/blog/nextra-3#-syntax-no-longer-works-for-latex

I tried the alpha version, indeed, it does not contain such a bug. Big thanks!
