build directory not self-sufficient anymore?

Describe the bug

I am not sure but it seems that there is a bundling problem in the latest version of svelte-kit.

Reproduction

https://stackblitz.com/edit/sveltejs-kit-template-default-tvp61o

Create a typescript skeleton project:

npm init svelte@next my-app
cd my-app
npm install
npm i -D svelte-i18n @sveltejs/adapter-node@next 

use adapter-node in svelte.config.js:

import adapter from '@sveltejs/adapter-node';
import preprocess from 'svelte-preprocess';

/** @type {import('@sveltejs/kit').Config} */
const config = {
	// Consult https://github.com/sveltejs/svelte-preprocess
	// for more information about preprocessors
	preprocess: preprocess(),

	kit: {
		adapter: adapter()
	}
};

export default config;

and build the project npm run build

The generated file build/server/entries/pages/index.svelte.js is:

import { c as create_ssr_component } from "../../chunks/index-2dc61825.js";
const Routes = create_ssr_component(($$result, $$props, $$bindings, slots) => {
  return `<h1>Welcome to SvelteKit</h1>
<p>Visit <a href="${"https://kit.svelte.dev"}">kit.svelte.dev</a> to read the documentation</p>`;
});
export { Routes as default };

Now import svelte-i18n in src/routes/index.svelte

<script lang="ts">
  import 'svelte-i18n';
</script>

<h1>Welcome to SvelteKit</h1>
<p>Visit <a href="https://kit.svelte.dev">kit.svelte.dev</a> to read the documentation</p>

rebuild, the generated file build/server/entries/pages/index.svelte.js is now:

import { n as noop, a as safe_not_equal, b as subscribe, r as run_all, i as is_function, c as create_ssr_component } from "../../chunks/index-110612cb.js";
import { __assign, __extends, __spreadArray } from "tslib";
...

The build directory now needs node_modules with all necessary imports.

Is this a duplicate of #3176? It sounds like it might be.
