4.1.0 breaks build with `additionalAliases: ['process']`

[ShGKme]

Error

After upgrading from 4.0.0 to 4.1.0 when additionalAliases: ['process'] is enabled, there are many errors like:

ERROR in ./node_modules/axios/lib/utils.js 678:42-49
Module not found: Error: Can't resolve '/home/shgk/nextcloud/server/apps-extra/spreed/node_modules/node-stdlib-browser/cjs/proxy/process' in '/home/shgk/nextcloud/server/apps-extra/spreed/node_modules/axios/lib'
Did you mean 'process.js'?
BREAKING CHANGE: The request '/home/shgk/nextcloud/server/apps-extra/spreed/node_modules/node-stdlib-browser/cjs/proxy/process' failed to resolve only because it was resolved as fully specified
(probably because the origin is strict EcmaScript Module, e. g. a module with javascript mimetype, a '*.mjs' file, or a '*.js' file where the package.json contains '"type": "module"').
The extension in the request is mandatory for it to be fully specified.
Add the extension to the request.

Reproduction

1. Clone https://github.com/nextcloud/spreed (use tag v21.0.1 for a specific version)
2. npm i -D node-polyfill-webpack-plugin@4.1.0
3. npm run dev

I'll try to make a smaller reproduction later.

I'm also experiencing the same issue after upgrading from 4.0.0 to 4.1.0. It's not just process that wasn't polyfilling, Buffer also wasn't working. I had to downgrade to 4.0.0 and the builds started working again.
