It works to me... You can check you manifest with validator http://manifest-validator.com/.

W3C only says the document (HTML file that have manifest attribute) must be same origin source with the manifest, they don't tell URL of resources must be too... You should read it carefully (at here). I also found the cross-site URL in W3 example (check here), that means it works correctly...

Finally, DON'T TRY TO PUT MANIFEST FILES ON CDN, JUST PUT IT IN YOUR SERVER AND LINK RESOURCE TO CDN. Manifest files have to have the same origin as their master entries, which includes their HTML files, and the browser checks the manifest file to see if its list of HTML pages has changed, rather than checking your HTML page to see if it points to a different manifest file.
