Description
Have this issue when passing css() extension for CodeMirror from here : https://www.npmjs.com/package/@codemirror/lang-css. This issue is not happening when downgrading to @uiw/react-codemirror 4.8.1. I also need @uiw/codemirror-themes package and it gives same unrecognized extension value error when using with an old version. I found this @uiw/codemirror-extensions-langs package that works fine but it's size is very big and I need only certain things from there. Is there any solution to use @codemirror/lang-* packages with latest version of @uiw/react-codemirror ?
Unfortunately I couldn't replicate that issue in sandbox as an example
@codemirror/state/dist/index.cjs logs
Old version
New version
npm ls @codemirror/state gives same versions

Start by comparing @uiw/react-codemirror 4.8.1 with the latest version and inspect the reported @codemirror/state dependency output from npm ls. Reproduce the error with @codemirror/lang-css and @uiw/codemirror-themes; done means these extensions work without the unrecognized extension value error.
