Svelte Adding class="<svelte-component-identifier>" to meta/link/script tags in the <svelte:head></svelte:head>

[redesigned]

Describe the bug

Svelte Adding class="" to meta/link/script tags in the svelte:head if there is a style block on the component. These elements should not have a class attribute and are not styleable.

Is there a reason for this, I'm not understanding? Or is this a bug that needs fixing?

example: <meta name="author" content="Re:Designed" class="s-Oo-daCANuhh7">

Reproduction

<svelte:head>
	<meta name="author" content={author} />
	<link rel="author" href={author_url} />
	<script type="application/ld+json"></script>
</svelte:head>

<div class="credits">
Site by <a href={author_url} target="_blank" rel="noopener noreferrer author" title={`Authored by ${author}`}><nobr>{author}</nobr></a>
</div>

<script lang="ts">
	interface Props {
		author?: string,
		author_url?: string,
	}
	let {
		author = 'Anonymous',
		author_url = 'https://example.com',
	}: Props = $props()
</script>

<style>
</style>

Remove the empty style block and the classes go away.

I have components that both add things to the head and have styleable blocks, but nothing in the head is styleable and i don't think it should ever have a class applied to it, correct?

Besides bloating the HTML and not having any valid meaning/effect it doesn't seem to be hurting anything, but I figured I should report it and see if it could be resolved if it isn't intended.

Many Thanks!

IIRC, in dev mode for the sake of HMR, styles get appended with * {}, plus there is no special handling for svelte:head or head elements.
