Steps to reproduce

In the repro, you can see multiple defineModel() macros, none of them throw a type error, even if the types don't match the Item interface.

e.g.:

interface Item {
  id: number;
  name: string;
}

defineModel<Item>("foo1", {
  default: () => ({ id: 1, name: 123 }), // 'name' should be of type 'string'
})

What is expected?

A type error should be thrown for the defineModel() default values.

What is actually happening?

No type error is shown.

Any additional comments?

It also behaves kinda strangely with basic types: playground
