Very nice article 🙂 Once this is turned on by default I’ll start using it for internal systems (with very graceful degradation of course!).

All the code also runs in Opera 24 by the way (after switching on the Experimental web platform features flag). Not really that surprising as we’re Chromium based, but all this canary-talk seems a bit strange. It does seem to work in current Opera 24 developer (which is Chromium 37, also in dev stream).
