Sphinx-hoverxref not working properly with Jupyter-Book?

[mscharling]

Describe the bug

I'm currently trying to implement sphinx-hoverxref in my Jupyter Book and I can't make it work. I'm mostly interested in the {term} part of hoverxref.

When I use {term}´word´ nothing shows not even the "word" itself. And, not even an error shows in the console when building the book.

I have posted the problem here aswell.

Reproduce the bug

1. Add the following insise _config.yml

sphinx:
  config:
    ...
    hoverxref_roles: term

2. Inside a .md-file write a small text with {term}´something in here´ and make sure that you have added "something in here" in your glossary.

3. Build your book.
