Hot reloading not picking up changes to rails CSS

[DEfusion]

I've tried making changes to both applicaiton_non_webpack.css and application_static.scss but I have to do a refresh in order for them to be picked up.

# application.html.erb
 <%= env_stylesheet_link_tag(
      static: 'application_static',
      hot: 'application_non_webpack',
      media: 'all'
    ) %>

<!-- output -->
<link rel="stylesheet" media="all" href="/assets/application_static.self-a63c83d31995d61cb5a658d5e5ee02cc80232bb2ac87c8d12cfc28036f82c8e3.css?body=1" />
<link rel="stylesheet" media="all" href="/assets/application_non_webpack.self-af04b226fd7202dfc532ce7aedb95a0128277937e90d3b3a3d35e1cce9e16886.css?body=1" />

I'm not sure what I've done wrong, changes to JSX files or the related component scss get picked up -- but I'm not sure I want to use CSS modules in my project. Is there a way to get the main stylesheets hot reloading?

I get the exact same behaviour by checking out this project too.

Hot reloading is functionality provided by the use of the Webpack Dev Server: http://andrewhfarmer.com/understanding-hmr/

It doesn't work on code that Webpack is not watching.
