Web fonts not loading in Chrome Web Store?

I've come across an issue on Chrome Web Store.

Web fonts refuse to load. I though perhaps it was because I had the 'App can run offline enabled' so I disabled it and they still didn't load.

Here is the link to the game on Chrome web store.

Here is the exact same files uploaded to Newgrounds where the web fonts work perfectly.

I also have an online leaderboard that is accessed at the end of the game which doesn't let you post scores on the chrome web store but works on newgrounds. so it appears chrome web store is blocking internet access to the app. Is there something I need to add or remove from the manifest.json or background.js or any other file? what would be causing this issue?

thanks,

carl

I have the same problems with Ouya games.

And I'm having this same issue. Web Fonts load when I run on the local host. If I paste the url and family name exactly into the Chrome Web Store App, it becomes a serif font.
