Extending sections or using mixins in plugin sections doesn't work as expected

[tobimori]

Description

This is what I tried:

index.php

App::plugin('tobimori/test', ['sections' => ['submissions' => ['extends' => 'pages']]];

Submissions.vue:

<script>
export default { extends: "k-pages-section" };
</script>

Result shows the empty pages section but clearly shows that no props are delivered (headline missing)

Let me know if you need anything else
