[Bug report] Webpack bundler has issues packing

[Mister-Hope]

Description

Starting from beta.51, it seems that webpack can not correctly resolve packages (or perform a much stricter esm check in all libraris)

So that a lot of 3rd party pacakges are triggering issues.

Meanwhile older versions and vite is not affected.

Reproduction

https://github.com/Mister-Hope/comment-bug-report

Giscus is not publishing any new versions for months, and it's all been working well, also the lit and giscus package is not broken, all providing standard esm.

Used Package Manager

pnpm

System Info

Cannot output
