Specifying output.filename disables auto-minify in production mode

[andybarron]

Do you want to request a feature or report a bug?
Bug

What is the current behavior?
Specifying output.filename in webpack.config.js disables output minification in production mode. When commenting out that single line of config, it works as intended.

If the current behavior is a bug, please provide the steps to reproduce.
Specify output: { filename: 'foo.js' } } and mode: 'production' in Webpack config and run webpack CLI

What is the expected behavior?
Always minify the output bundle.

If this is a feature request, what is motivation or use case for changing the behavior?

Please mention other relevant information such as the browser version, Node.js version, webpack version, and Operating System.
Node 8.9.4, Webpack 4.1.1, macOS 10.12.6

Cannot reproduce with Node v8.9.4 and webpack 4.1.1. Could you attach an example?

I don't think this is a bug, but a user error instead.

I am able to reproduce this consistently by un-commenting the file name line. That said, the file name did have a query string attached to it for cache busting. I'll try removing that when I get a chance. (I would still consider that a bug, but I have no idea if that is actually the issue.) This is a private repository, but I will see if I can assemble a minimal example as well.
