`Uncaught TypeError: stopwords.indexOf is not a function` when searching after updating to Sphinx 9

[vivaria]

I'm seeing the following uncaught error in the browser console:

sphinx_immaterial_theme.32136f45f91ae6956.min.js?v=a7a9472a:14 Uncaught TypeError: stopwords.indexOf is not a function
    at sphinx_immaterial_theme.32136f45f91ae6956.min.js?v=a7a9472a:14:73803

    at i (sphinx_immaterial_theme.32136f45f91ae6956.min.js?v=a7a9472a:1:1060)

And search is empty (other users have reported this same behavior):

Here's the dependency diff between the last passing build and the newest build: https://www.diffchecker.com/EIOWRx5F/

And here's my conf.py:

Might just be a dupe of #475, but I wanted to mention it anyway in case it has an effect on #484, since I'm not seeing any search results for "stopwords.indexOf".

Possibly related:

• Quick search does not work in some page python/cpython#142222
• Convert stopwords to a JavaScript set sphinx-doc/sphinx#13575

Thanks for the report!

This is definitely related to #475, but it is good to have a separate issue because

1. This was not caught in unit tests, nor was mentioned in Sphinx v9.0 breaks theme #475.
2. Sphinx v9 support #484 does not fix this issue.
