**What did you do?**	
<!-- Please include the actual source code causing the issue. -->
```vue
// CommentCard.vue
<template>
  <!-- ... -->
  <CommentCard />
  <!-- ... -->
</template>
<script setup lang="ts">
  // ...
</script>
```

**What did you expect to happen?**

No error 


**What actually happened?**
<!--
  Please include the actual, raw output from ESLint.
  If you are only looking at the results of your editor extension, also check the CLI results.
-->

```
/home/mister-hope/projects/waline/packages/client/src/components/CommentCard.vue
  152:9   error    The '<CommentCard>' component has been used, but not defined                                                               vue/no-undef-components
```

I would happy to share more if you do need this, but I do think that it's easy to make a repro, and the test file is not containing the test case where a component using `<script setup>` use itself in template.
