Steps to reproduce

https://stackblitz.com/edit/vitejs-vite-nctods?file=src%2FApp.vue

App.vue defines a generic as well as uses defineModel with a custom name containing dash.
Run pnpm test to type-check the project, and the weird error will occur:

App.vue:1:34 - error TS2304: Cannot find name 'A'.

1 <script setup lang="ts" generic="A">
                                   ~

A grammar error occurs if multiple generic parameters are present:

App.vue:1:35 - error TS1005: '>' expected.

1 <script setup lang="ts" generic="A, B">
                                    ~

Try to remove a dash from hello-world and see the both errors go away.

What is expected?

No such errors

What is actually happening?

They do occur
