Media query test fails on Windows

I grabbed a copy of the project and ran `gulp test` and one test failed. It seems to be because of how Windows handles line breaks because the CSS is the same. I ran the same code and tests on a Mac and all tests passed. Maybe the issue is upstream but I'll start here.
