Steps to reproduce

1. In tsconfig.json, set "declaration": true
2. Write an SFC with a script setup block and an attribute naming a generic, like generic="T"
3. Write a props interface using the generic and pass it to the type parameter in defineProps
4. Observe a type error saying "Default export of the module has or is using private name"

What is expected?

This should not trigger a type error, which is how it works when no generic attribute is provided.

What is actually happening?

There is a type error saying "Default export of the module has or is using private name"
