Thanks Oliver! Found it.  In this case it was a mixup between core_h5p and plugin mod_hvp.

For anyone struggling with the same issue:

Moodle 3.9 has a h5p implementation in core and the contentbank is preferring this over the mod_hvp plugin.
The core_h5p is using own libraries.

Install MathDIsplay library in core_h5p

1. Open the libraries-list under "Manage H5P content types" (/h5p/libraries.php), click the tab "Installed H5P libraries".
2. Check if "MathDisplay" is present. If not get it from here (there is a download link on the page) and upload it with the form on the same page. (The naming "Upload H5P content types" is a bit misleading here).

Adjust settings for local MathJax installation

The default setting of this library is to use the public mathjax-cdn. if you want to change that you have to modify your config.php by adding:

$CFG->core_h5p_library_config = array(
  "H5P.MathDisplay" => array(
    "renderer" => array(
      "mathjax" => array(
        "src" => "/mathjax/MathJax.js",
        "config" => array(
          "extensions" => array("tex2jax.js"),
          "jax" => array("input/TeX", "output/HTML-CSS"),
          "tex2jax" => array(
            // Important, otherwise MathJax will be rendered inside CKEditor
            "ignoreClass" => "ckeditor"
          ),
          "messageStyle" => "none"
        )
      )
    )
  )
);

Adjust the "src" to point to the local mathjax installation. An absolute address (https://yourhost/...) will work, too.
Be sure to use "$CFG->core_h5p_library_config". The documentation on the h5p-website is for the mod_hvp plugin  wink

Clear caches and it should work.
