TypeScript with type-only props declaration: exclusion of an enum breaks the property check

[XavierChevalier]

Vue version

3.2.37

Steps to reproduce

• Use Type-only props declaration
• Create an enum and try to exclude one of element.

// Position.ts
export enum Position {
  First = 'FIRST',
  Second = 'SECOND',
  Third = 'THIRD',
}

<!-- Child.vue -->
<script setup lang="ts">
import { Position } from './Position.ts';

type FirstAndSecond = Exclude<PositionList, PositionList.Third>; // PositionList.First | PositionList.Second

defineProps<{
  position: FirstAndSecond;
}>();
</script>

<!-- Parent.vue -->
<script setup lang="ts">
import { Position } from './Position.ts';
</script>

<template>
  <Child :position="Position.First" /> <!-- [Vue warn]: Invalid prop: type check failed for prop "position". Expected Object, got String with value "FIRST". -->
</template>

What is expected?

No warning error

What is actually happening?

[Vue warn]: Invalid prop: type check failed for prop "position". Expected Object, got String with value "FIRST".

Any additional comments?

This works perfectly when there is no exclusion and the enum is used directly.
