pydata-sphinx-theme 0.13.2 breaks sphinx-book-theme #711
Description

After pydata-sphinx-theme updated to 0.13.2, our sphinx-build job in http://github.com/google/jax showed the following error:

We are pinning to pydata-sphinx-theme==0.13.1 for the time being to fix the error.
- Our requirements file is here: https://github.com/google/jax/blob/main/docs/requirements.txt
- Our readthedocs config is here: https://github.com/google/jax/blob/main/.readthedocs.yml
The breaking change in pydata-sphinx-theme seems to be this one: pydata/pydata-sphinx-theme@fc975d0
I'm reporting here because it looks like sphinx-book-theme is using an API that is intended to be private.
