LaTex render is not working on 1.9.9 containerized on Rocky Linux 9.3

[mcorvo]

Description

I've recently upgraded the VM hosting Hedgedoc to a Rocky Linux release 9.3 (Blue Onyx). Hedgedoc is installed as a container (latest version 1.9.9) and run with Docker version 24.0.7. The database is a Postgres with image 16.1-alpine3.19.
When the user enters some LaTex code, it is not rendered at all. I tried with the old instance (Hedgedoc 1.9.9, Postgres 14.5-alpine, Docker 23.0.3 on Centos 7.9) and it works correctly, so my guess is that the issue may be related to the new OS on which I'm running.

Steps to reproduce

1. Open the Feature pages
2. Go to the LaTex section
3. Look at this code \sum_{i=1}^n i^2 = \frac{n(n+1)(2n+1)}{6}

Expected behaviour

I should see the code rendered by the MathJax engine, but the code is displayed "as is" in plain text.

Instead of:

$$\sum_{i=1}^n i^2 = \frac{n(n+1)(2n+1)}{6}$$

The mis-rendering was my fault: I decided to terminate the TLS connection on an Apache reverse proxy, but I set the parameter CMD_PROTOCOL_USESSL to false. For some reasons I honestly don't understand, the MathJax library was not able to work correctly. Once set the parameter to "true" everything worked fine.
