Build fails after upgrading to vite > 2.9.0

See original GitHub issue

Describe the bug

It’s expect to build the project when, in a dependency, I export a svelte component, and then import that component. However the build fails with this error:

500

Unknown file extension ".svelte" for /home/projects/vitejs-vite-14hxgx/node_modules/@higenku/theme/src/footer/Footer.svelte

TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension ".svelte" for /home/projects/vitejs-vite-14hxgx/node_modules/@higenku/theme/src/footer/Footer.svelte

You can check it yourself here

this should have fixed the problem, however It hasn’t

Reproduction

Open https://stackblitz.com/edit/sveltekiterror and see the error yourself

install the next version of my theme @higenku/theme@0.6.6-next other versions work because you have to import the components yourself.
Import a component (I only exported the footer ones to test the vite 3 update)

<script lang="ts">
import {Footer} from "@higenku/theme"
</script>
