Svelte preprocessor gives false message

Describe the bug

I have the following code:

<svelte:head>
  {#if browser}
    <script src="/app.js"></script>
  {/if}
</svelte:head>

This code does work but I get the following message in my yarn dev terminal: [svelte-preprocess] The file "/app.js" was not found.

app.js is saved in the static directory.

Reproduction

Have the following code snippet in some .svelte file.

<script lang="ts">
  import { browser } from '$app/env';
</script>

<svelte:head>
  {#if browser}
    <script src="/app.js"></script>
  {/if}
</svelte:head>

annoyance

Additional Information

cookie.js is the exact same case.

from what i'm reading here it looks like svelte itself parses the extra <script> tag inside svelte:head and passes it to svelte-preprocess which then tries to load the src file as external content https://github.com/sveltejs/svelte-preprocess#external-files
