A potential memory leak occurs in Nuxt on the client side when dynamically loading a component

I'm currently working on a NuxtJS application where I need to dynamically load components. While my code successfully loads the component on the server-side, the browser seems to encounter a significant memory leak during page loading, making it impossible to perform a performance analysis or memory heap snapshot.

My current code setup looks like this:

/plugins/theme-load-method.js

import Vue from 'vue';

export default function ({store}) {
  Vue.prototype.loadThemeTemplate = function loadThemeTemplate(template) {
    return () => import(`~/components/themes/${store.state.config.theme}/${template}`);
  };
}

pages/index.vue

<template>
  <component :is="loadThemeTemplate('index.vue')" />
</template>

<script>
export default {
  name: "HomePage"
};
</script>

components/themes/MY_THEME_1/index.vue

<template>
    <section>
        MY_THEME_1 Home Page
    </section>
</template>

<script>
export default {
  name: "ThemeHomePage",
}
</script>

Any insights on why this memory issue is happening only on the client-side would be greatly appreciated!

According to the information provided in the documentation: https://nuxtjs.org/docs/directory-structure/plugins/#inject-in-root--context

Avoid using Vue.use(), Vue.component(), and refrain from making modifications to the Vue prototype or global Vue object within the function that your plugin exports. Doing so could lead to a memory leak on the server-side. Refer to global mixins for additional details.

Therefore, it is recommended to customize Vue.prototype.loadThemeTemplate outside of those exported functions.
