@license comments are not preserved during build

Is this a bug report?

Yes

Did you try recovering your dependencies?

Yes. Yarn version: 1.6.0

Which terms did you search for in User Guide?

I was asked to file a bug report in issue #4116.

Environment

npx: installed 67 in 14.97s

Environment:
  OS:  macOS High Sierra 10.13.3
  Node:  9.7.1
  Yarn:  1.6.0
  npm:  6.0.0
  Watchman:  Not Found
  Xcode:  Xcode 9.3 Build version 9E145
  Android Studio:  Not Found

Packages: (wanted => installed)
  react: ^16.0.0 => 16.4.0
  react-dom: ^16.0.0 => 16.4.0
  react-scripts: ^1.1.4 => 1.1.4

Steps to Reproduce

1. ./src/index.js contains the following comment:

/**
  * @license Copyright (c) Conscious Apps Inc. All Rights Reserved.
  * Written by Martin Adams https://github.com/heymartinadams
*/

1. Run react-scripts build.

Expected Behavior

On running react-scripts build, however, comment isn’t preserved in resulting ./build/static/js/main.*.js file, even though (as issue #4116 states), create-react-app ought to preserve JSDoc-style comments.

Actual Behavior

Missing @license comment in ./build/static/js/main.*.js file.

Mmh… I still didn’t get it (in some areas, like git, I’m a complete beginner). How about this? It’s not a high-priority issue for me, and I trust you all, so if you say you fixed it, pretty sure it works? (Sorry, don’t mean to be difficult, just super focused on a project and can’t spend too much time on other things at the moment.)
