Refused to execute script from

I'm getting an error in console:

```
Refused to execute script from 'https://raw.github.com/itsthatguy/gridwax/master/gridwax.js' because its MIME type ('text/plain') is not executable, and strict MIME type checking is enabled.
```

Start with gridwax.js at the raw.github.com URL and reproduce the console error in a browser. Check how the script is being served and determine the supported way to load it; done when the script executes without the reported MIME-type refusal.
