Setting "codemirror-theme" doesn't work

[DSSAtDatagen]

Describe the bug

When I set a codemirror theme, it doesn't seem to change anything; the colors remain the default.

I tried adding this to conf.py, as instructed at https://sphinx-thebe.readthedocs.io/en/latest/configure.html#choose-a-codemirror-theme:

thebe_config = {
   "codemirror-theme": "dracula"
}

Out of desperation, and in case there was an error in the documentation, I even tried this:

thebe_config = {
    "codeMirrorConfig": {
        "codemirror-theme": "dracula",
        "codemirror_theme": "yeti"
    },
    "codemirror-theme": "ayu-dark",
    "codemirror_theme": "cobalt"
}

codemirror_theme = "colorforth"

codeMirrorConfig = {
    "codemirror-theme": "hopscotch",
    "codemirror_theme": "liquibyte"
}

None of them worked.

Reproduce the bug

1. Add

thebe_config = {
   "codemirror-theme": "dracula"
}

to your conf.py file

2. Build your documentation
3. Open your documentation and see that the colors have not changed

List your environment

It seems like this has to do with #25, though it might be stale.
