Seems to be a global problem, I even tried it on Browserstack (and Chrome, Safari, and Firefox on my Mac, and Chrome on Android on my phone).
I get an error like this 3 times:
Repl.72693ad3.js:4 Uncaught (in promise) Error: Unrecognized extension value in extension set ([object Object]). This sometimes happens because multiple instances of @codemirror/state are loaded, breaking instanceof checks.
