After we comment the prop in __returned__, the error will disappear:

See https://github.com/microsoft/TypeScript/issues/42873

Not really an issue that Vue can fix, since we do have correct dependency relationships between the packages.

But if you are trying to emit types for your Vue components, you should use vue-tsc instead (this is what powers Volar internally)
