Just check the response time for clicking event. There's a short delay for HTML5 click (which is by design to differentiate click event and double-tap-to-zoom-in event).
My guess is that, at least the list of conversation is in HTML5 for sure. I though the message content would also be in HTML5 but it seems the "reply" icon responds very fast. Maybe some buttons were re-implemented using native code.
