Components dont have default export with multiple <script>

[Nisgrak]

Version

3.2.4

Reproduction link

https://github.com/Nisgrak/test-setup-ts

Steps to reproduce

1. Init the proyect with yarn serve
2. See the error that happen with HelloWorld components

What is expected?

Can export interfaces and other vars in a normal <script> tag having an <script setup> one

What is actually happening?

An error with the default export of the HelloWorld component

---

I try to create a interface of the props of a components and export it, using the new <script setup>, but it don't work and in the docs it says if have to export something must be in a normal <script>

Maybe a duplicate of #4294 as it seems that you can import what is exported in other files

[Nisgrak]

It give another error, I create a branch for the example, moving the export in the <script setup> tag

[Nisgrak]

It seems if I add this to the bottom of the <script> tag works, but cant use the interface to declare the prosp inside <script setup>, it's need to exist inside the setup, but there can't be exported, strange...

export default defineComponent({});

I created the branch workaround in the repo with this fix If you need to test it, thanks!

@posva I try with the new version 3.2.6 but stay the same

It seems caused by IDE plugin.Vetur doesn't support it now, you can try Volar instead.

I use Volar @Bigfish8. How an IDE plugin can affect the compilation of Vue?

Sorry, I was misleaded by the picture.It is indeed a compilation bug.

I'm still having this issue in 3.2.9. I've been using the workaround Nisgrak and if I remove it in 3.2.9 the errors about SFCs not having a default export come back.
