If this issue only occurs in one browser, which browser is a problem?

Describe the Bug

Importing a js-file with the ?url directive and then passing the string to a child component works in dev mode but breaks in build mode.

I have three files

pages/
     index.astro
     script.astro
components/
     Component.astro

with the content

// script.ts
export const hello = (user: string) => 'Hello, ' + user + '!';

// Component.astro
---
const { ref } = Astro.props;
const { hello } = await import(/* @vite-ignore */ref);
---

<div>{hello("Server")}</div>
<div id="clientdiv"></div>

<script define:vars={{ ref }}>
    import(/* @vite-ignore */ref).then((module) => {
        document.querySelector("#clientdiv").textContent = module.hello("Client");
    });
</script>

// index.astro 
---
import Component from '../components/Component.astro';
import ref from './script.ts?url';
---

<Component ref={ref} />

This works in dev mode but breaks during build with error Cannot find module '[...]/_astro/script.CnRJZ0uG.ts'

What's the expected result?

The expected result is

Hello, Server!
Hello, Client!

My goal here is to have a piece of code which is executed during build but potentially also on the client for user interactivity. I know that only serialisable objects can be passed to client components, that's why I am trying to import the same external script in both places. This approach works if I hard-code "script.ts" in Component.astro but I would like to have a generic component.
