which leads to unexpected behaviour.
When you do this:
var options;
options = this._options;
options.inTrash = true;
Navigation.navigate(app.router.routes.trash, options);
Then the options hash that is put on the backstack is the same as this._options
So when you navigate back, the stack already contains state.inTrash for the previous state. Difficult to explain. But easy to run into if you not construct the state from scratch each time you call Navigation.navigate. The question is: Why does it not clone
the state object but instead just saves a reference to it?
