Two JSON-LD tags

[shuaixr]

Describe the bug

Sveltekit generates two JSON-LD tags when configured with a domain in a production environment, here's a comparison between the domain and non-domain versions: http://45.56.85.226:3000/ and https://jsonld.shuaixr.xyz/

When JavaScript is turned off in the browser, one of the JSON-LD tags disappears, so I didn't pay too much attention to it initially. However, recently I found that there were also two in Googlebot's crawled pages.

Also, I wrote a Svelte component like this for easy use of JSON-LD:

<script lang="ts">
	export let json_ld: unknown;
</script>

<svelte:head
	>{@html `
    <script type="application/ld+json">
            ${JSON.stringify(json_ld)}
    </script>`}
</svelte:head>

I am a beginner, this error may also be caused by my non-standard svelte component. If so, please inform me of the correct way.
I created a repository to reproduce the bug where there is all the code:https://github.com/shuaixr/jsonld_svelte
I created a website deployment of this repository:
https://jsonld.shuaixr.xyz

Reproduction

1.clone https://github.com/shuaixr/jsonld_svelte
2.npm run build
3.export PROTOCOL_HEADER=x-forwarded-proto && export HOST_HEADER=x-forwarded-host
3.node build/index.js

Which should have been fixed by sveltejs/svelte#7745

Can you try updating the svelte package and see if this still occurs?

The error disappeared when I updated @svelte/kit to version 1.3.6. Thank you.
