Expected/desired behavior

Minimal reproduction of the problem with instructions npm run build:universal-prod

Please tell us about your environment:

Thanks !

I solved this by forcing the uglify-js deps to use version git://github.com/mishoo/UglifyJS2#harmony-v2.8.22.

Get the latest version of this repository, and remove webpack and uglify-js dirs from node_modules and run npm install/yarn et voila!
