I don't get it. Isn't that a type error?

You're right, it does show up in the playground but not when running locally. I updated the issue with the new repro link.

I made a repro repo from using npm create vue@latest: https://github.com/richardsimko/vue-bug

Running npm run type-check only outputs the following error:

Now it's back to not working in the playground either... Not sure what was going on before.
