So I remember reviewing the ticket that introduced this that I was surprised that you needed to call [restore](https://github.com/wymeditor/wymeditor/blob/master/src/test/unit/test.js#L1014), since I thought sinon-qunit made this automatic. Now it makes sense why you needed to do that. I think it's probably still a good idea, though. Otherwise, you'll get bleed if you call `setupTable` and then do something else that should move the selection.
