CORS issue on demo page (also https issue)

[joeytwiddle]

If I visit the demo page http://standardjs.com/demo.html, I cannot format the code. I see this in the Firefox console:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://standardizer.flet.io//lint. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).

And this in Chrome's console:

XMLHttpRequest cannot load https://standardizer.flet.io//version. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://standardjs.com' is therefore not allowed access. The response had HTTP status code 404.

I am running UBlockOrigin in both browsers, but I still get the error even if it's disabled.

And by the way, I also tried accessing the demo page over https, but both browsers complained because the certificate is assigned to *.github.com.
