module.exports = {
  root: true,
  extends: ["plugin:vue/vue3-essential", "eslint:recommended"],
  parserOptions: {
    ecmaVersion: "latest",
  },
};
```

**What did you do?**	
<!-- Please include the actual source code causing the issue. -->
```vue
<template>
  <Transition> <div>Hello</div></Transition>
</template>
```

**What did you expect to happen?**
It should show a red wavy warning of [vue/require-toggle-inside-transition](https://eslint.vuejs.org/rules/require-toggle-inside-transition.html) on the VSCode because there is no v-if of v-show.


**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.
-->
It doesn't show any red wavy warnings if there are spaces or line breaks before the element.
