The VisualEditor isn't perfectly rendering markup yet (which is understandable), and even when it does it'll look slightly different from read mode in a lot of ways. The problem is that cancelling the VE editing interface, or saving, loads a VE-rendered article view rather than what the article actually looks like.

(sorry if this sounds nonsensical; it's difficult to explain at this end).
