Stubtest does not like that the typeddicts are "public", as it sees them and not included at runtime.

You may be able to fix this with __all__, though you would probably have to include that in the C extension as well, so may not be worth it.

Prefixing the class names with _ silences the warnings.

Alternatively, you could define the Typed Dicts in a private module and import them.

Making them private seems the simplest, and still seems to work for mathtext.
