Is this an easy bug?

To further clarify what the issue here is:

• a user visits https://www.mediawiki.org/wiki/Wikimedia_Engineering/2012-13_Goals;
• user clicks "edit";
• VisualEditor form loads;
• user tries to escape the form by pressing the "back" button in his/her browser;
• browser's "back" button doesn't work as expected (it should take the user back to the implicit view action where he/she started).

We currently use ?veaction=edit as trigger for VisualEditor from a permanent url.

This is implemented by checking the query parameter on page load and triggering init (just like a click on "VisualEditor" would do), and then we replace (without refresh) the url to drop this query parameter using the HTML5 History api (replaceState).

I'd recommend we build on this by using pushState when VisualEditor is initialised (we can then remove the current behaviour as there's no longer any reason to remove it from the url).

Note that it is slightly more complicated than just calling replaceState on init. We also need to listen on('popstate') to move back to read mode if the user presses Back to a url within the history that contains HTML5 history state data from VisualEditor.

Setting milestone to 2013-06-27 since it is marked as blocker for "Beta" (2013-07). It may be moved to an earlier milestone as we see fit. But no later than 06-27. Setting it since I use milestone to sort "My bugs".

Merged and will go out with wmf7 (from tomorrow).

This seems to be broken again (back button changes URL but doesn't take user back to read state)
