vue/multi-word-component-names doesn't catch SFCs with setup script?

[vincerubinetti]

Not sure if this is a bug or a question, but it's certainly strange to me. If it's intentional it should be noted somewhere.

I was linting a project made with vue-cli, and noticed that some single-word component files weren't being caught by the linter, and some were. The ones that were being caught were ones with just a <template>, and the ones that weren't had a <script setup>.

Here's a minimum reproducible example (at least in my project setup); three variations of a file incorrectly named Test.vue:

Caught ✅ (lint check fails)

<template>
  <p>test</p>
</template>

Caught ✅ (lint check fails)

<template>
  <AppButton />
</template>

<script lang="ts">
import { defineComponent } from "vue";
import AppButton from "@/components/AppButton.vue";

export default defineComponent({ components: { AppButton } });
</script>

Not caught ❌ (lint check passes)

<template>
  <AppButton />
</template>

<script setup lang="ts">
import AppButton from "@/components/AppButton.vue";
</script>

Here is my `package.json`:
