import.meta.PLUGIN_WEB_EXT_CHUNK_CSS_PATHS doesn't contain all CSS files referenced

[1mehal]

I'm trying to load into shadow dom a simple page

<script lang="ts">
	import { Avatar } from '@skeletonlabs/skeleton';
</script>

<div>
	<h1>My New Web Extension</h1>
</div>
<Avatar src="https://i.pravatar.cc/" />
<style>
	:host {
		position: fixed;
		display: inline-block;
		top: 29px;
		right: 20px;
		z-index: 99999999;
	}
</style>

This requires to load Skeleton UI css, however in import.meta.PLUGIN_WEB_EXT_CHUNK_CSS_PATHS I only have 1 available CSS from my actual page, and the same in webAccessibleResources -> I don't have CSS files listed.

Is there any workaround for this?
