Request to MathJax.js responds with 404 and breaks the viewer

[ddadaal]

Describe the bug

The plugin is currently broken seemingly because viewer.js requests a MathJax.js from https://app.diagrams.net/math/MathJax.js?config=TeX-MML-AM_SVG-full which is now 404. Since the viewer.js is maintained in this repo, should this issue be resolved from here?

Thanks!

To Reproduce

The demo page is already broken. The viewer is not shown.

Expected behavior

The viewer should appear and show the image.

I can also confirm this in Linux. I can't make it work with anything "chrome-like" (I've tried Chrome, Thorium and Vivaldi).

But with Firefox I have found a very weird behavior:

When I tried to show several pages of the same diagram, I noticed that the first one appears to be blank (and when you click the "Fullscreen" button, it appears there; it's just the embedded drawio which doesn't work).

The rest, though, appears perfectly. Both in the embedded viewer and in fullscreen.
So I ended up with this (very) ugly workaround where I show the first page with opacity 0 and height 1px and then all pages (including the page 0 again), just to ensure it's rendered correctly:

import Drawio from '@theme/Drawio'
import sampleGraph from '!!raw-loader!./assets/test.drawio';

<div style={{opacity: 0, height: "1px"}}>
  <Drawio content={sampleGraph}
          page={0}
          toolbar={"zoom lightbox"}/>
</div>

Leyenda:
<Drawio content={sampleGraph}
        page={0}
        toolbar={"zoom lightbox"}/>

Diagrama de Contexto
<Drawio content={sampleGraph}
        page={1}
        toolbar={"zoom lightbox"}/>

DFD-0
<Drawio content={sampleGraph}
        page={2}
        toolbar={"zoom lightbox"}/>
