So upon updating to the latest ember version I noticed that renderTemplate hooks from multiple child routes, rendering into the same outlet of a parent template no longer replace one another when the route is visited, but rather append to each other in the template. So visiting child 1 route via transitionTo() and then child 2 of parent route would initially render child1 template, and then child2 template underneath child1 template and so on.
Is this a bug or a change that we need to adjust our code for? I haven’t been able to think of a solution to this other than possibly calling re-render on the parent route itself.
