Node v9.9.0, latest packages installed, sample project

I'm noticing a couple issues, not sure if it's a webpack bug or for this project:

1. Depending on the order in which chunks are loaded it's possible for styles to be inconsistently applied to the page
2. Possible missing documentation for using single css chunk.

The second seemed related to what @ezzatron was seeing in #116 with a single page app that was unresponsive since it's demonstrated (along with a potential fix) in my demo project.

I tried to include as much information on the issues in the demo project, but let me know if there's more that's needed to push this forward. Happy to help in any way I can.
