External library components break in rollup build (Vue3) #4089
Description
Describe the bug
Components imported from an external library stop working correctly after the final bundle is produced, even though vite dev loads them correctly.
I created a library package according to the docs, and used an exported component in an another application.
Things seem to disappear or simply stop working, namely templates/fragments and slots.
Nodes either just don't render, or errors like node is null are thrown. The latter happens with slots, but I don't have a MWE for that.
Reproduction
I created an example repo here.
steps:
- from
testlibyarnyarn buildyarn linkif needed
- from
testappyarn link testlibif neededyarnyarn dev- observe the correct result
yarn build && yarn serve- observe the void

- Read the docs.
- Check that there isn't already an issue that reports the same bug to avoid creating a duplicate.
- Make sure this is a Vite issue and not a framework-specific issue. For example, if it's a Vue SFC related bug, it should likely be reported to https://github.com/vuejs/vue-next instead.
- Check that this is a concrete bug. For Q&A open a GitHub Discussion or join our Discord Chat Server.
