There is not an obvious way to navigate from a post's edit history page back to that post in context. There should be. In the event I arrived at the history from the post itself, the back button does function (although a visible link would also be good), but in the case of following it from an external link or from notifications or whatever, there is actually no way to get there withouth going to the home page, hunting for the question, and opening it manually.
