Custom webpack in angular doesn't end the process

[MitkoTschimev]

Environment

node v18.16.0
yarn 1.22.19

Reproduction

angular project with custom webpack build and a simple unplugin webpack

Describe the bug

When I use a simple plugin like from the README the webpack build is finishing but not the process.

There is an open bug already in this repo reflecting the issue and we nailed it down to unplugin
getsentry/sentry-javascript-bundler-plugins#345

Additional context

I can confirm, it happens with Angular 14

Not sure if this helps, but we (TanStack Router) had a similar issue, where the webpack version of the plugin didn't ever end, during build.

With a bit of Googling, this was the fix we implemented: https://github.com/TanStack/router/blob/9616d0193bb3bdf9af60ee3475c30dfd30927416/packages/router-plugin/src/code-splitter.ts#L221
