Checklist

• I have tried restarting my IDE and the issue persists.
• I have read the FAQ and my problem is not listed.

Tell us about your environment

• ESLint version: 8.45.0
• eslint-plugin-vue version: 9.24.1
• Vue version: n.a.
• Node version: v20.5.0
• Operating System: macOS 14.3.1 (23D60)

Please show your full configuration:

module.exports = {
  root: true,

  env: {
    browser: true,
    es6: true,
    node: true
  },

  parser: "vue-eslint-parser",

  parserOptions: {
    sourceType: "module"
  },

  extends: [
    "plugin:vue/vue3-recommended"
  ],

  plugins: [
    "eslint-plugin-jsdoc",
    "eliottvincent"
  ],

  rules: {
    "eliottvincent/import-group-comment": "error",

    "jsdoc/require-jsdoc": [
      "error",

      {
        "contexts": [
          "Property[key.name=\"methods\"] > ObjectExpression > Property"
        ]
      }
    ]
  }
};

What did you do?

<template lang="pug">
.hello-world
  span {{ "Hello world" }}
</template>

<script setup>
// NPM
import { definePageMeta, useHead } from "#imports";
import { useI18n } from "vue-i18n";

definePageMeta({
  layout: "showcase"
});

useHead({
  title: "Hello World"
});
</script>

<script>
export default {
  methods: {
    // --> EVENT LISTENERS <--

    /**
     * Some function
     * @public
     * @return {undefined}
     */
    someFunction() {
      console.log("test");
    }
  }
};
</script>

What did you expect to happen?
I have two rules:

• a custom rule eliottvincent/import-group-comment: it ensures import statements are preceded by a comment stating their type
• a rule from the official plugin jsdoc/require-jsdoc: it enforces JSDoc comments on functions and classes

I expect both these rules to work in Vue SFC files.

What actually happened?

When a Vue SFC file contains two script tags, one with setup keyword (to make use of Vue Composition API) and a regular one, both of these rules will fail (check the file res/example/not_ok.vue in the repro example).

When a Vue SFC file contains only one script tag, these rules work fine (check the file res/example/ok_1.vue in the repro example).

When a Vue SFC file contains two regular script tags (no setup keyword), these rules work fine as well (check the file res/example/ok_2.vue in the repro example).

This is the raw output:

/vue-eslint-parser-script-repro/res/example/not_ok.vue
   8:1  error  Import "#imports" should be in the "NPM" group  eliottvincent/import-group-comment
   9:1  error  Import "vue-i18n" should be in the "NPM" group  eliottvincent/import-group-comment
  30:5  error  Missing JSDoc comment                           jsdoc/require-jsdoc

✖ 3 problems (3 errors, 0 warnings)
  1 error and 0 warnings potentially fixable with the `--fix` option.

Repository to reproduce this issue

I suspect the culprit is the getCommentsBefore method which returns an empty array when both rule fails.

Posting here as well since I don't know which repo is at fault. Thanks!
