This demo contains a ractive view with a component inside a transition element.
When the element is toggled in, the component is constructed before the transition completes :)
When the element is toggled away, the component is torn down before the transition completes :(
This doesn't look very good, since fancy components are destroyed before they become hidden to the user.
