How to show aside anchor link when using custom component?

[StreakingMan]

when I use h2 tag in custom component, It doesn't show aside anchor link:

Item.vue

<template>
    <h2>{{title}}</h2>
    <p>{{desc}}</p>
</template>

list.vue

<template>
    <Item v-for="(item, idx) in [{ title: 'hello', desc: 'word' }]" v-bind="item" :key="idx" />
</template>

article.md

<List />

I know that using v-for and # directly in Markdown can make it work:

<div v-for="(item, idx) in [{ title: 'hello', desc: 'word' }]" :key="idx" />

## {{ item.title }}

</div>

However, my scenario is complex, and I need to include the header within the custom component. Is there any API or workaround to implement this?

Thanks!
