css import / react-benchmark / webpack issue

[dustinfreeman]

I'm trying to run react-benchmark in my own app. The app works fine with yarn start normally, but I can't seem to get it to import css. I am not sure if this is a react-benchmark issue specifically, but would appreciate any help.

I have a minimal example here: https://github.com/dustinfreeman/bug-react-benchmark-css-import
