Vue3, Router4 problem when using externals

[juliusfriedman]

Describe the bug

only displays html comment vnode where router import should be.

Reproduction

https://github.com/juliusfriedman/vue-project

Steps to reproduce

Just run and build project in production mode (debug mode doesn't have the issue)

System Info

All systems but only when externalizing all depencies in production mode, if I run in debug or if I remove the externalization for vue-router everything works as expected, if I instead try to internalize vue and externalize vue-router other strange issues occur.

Used Package Manager

npm

Logs

No error in console etc.

I originally made this issue in VueJs/Router -> here but it was converted into a discussion with no answer....

Thanks in advance for your help!

If you require any additional information please let me know and I will provide ASAP!

One other question I had was how to enable the use of externals while debugging it doesn't seem supported in vite currently... #6582

I also notice that if I set resolve.alias to the same values I use in rollupOptions.output.paths that the bundles seem to resolve from the CDN and in debug mode I FINALLY get the same blank page I get in prod mode....
