Can't build custom components in production mode

Describe the Bug

Can't build custom components in production mode

Steps to Reproduce

1. open webpack.config.js in custom-components
2. change mode to production
3. npm start
4. Uncaught Error: No provider for "e"! (Resolving: rangeField -> e)

Environment

• Host Chrome
• OS: Macos
• Library version: 1.6.4

I can confirm this is still happening with library version == 1.8.3.
Error occurs in production mode, only if optimization.minimize set to true in webpack.conf.js

@maximryzhov custom-components/app/extension/render/index.js add:
CustomFormFields.$inject = ['formFields'];
