`RouterOutlet` uses a unique injector logic that returns a value that correspond to the `ActivatedRoute` token dynamically. This logic breaks when a component/directive/pipe that injects the `ActivatedRoute` is located within a `@defer` block, because defer creates an `EnvironmentInjector` instance, which doesn't have that dynamic logic.
We've added some special handling of the `OutletInjector` in one of the previous commits, but it was incomplete and it was not covering cases when different routes use the same component. This commit updates defer logic to re-establish this dynamic behavior for `ActivatedRoute` by creating an instance of the `OutletInjector` when a parent injector was also an instance of `OutletInjector`.
This fix is a short-term solution and longer term we should find a way to achieve the dynamic behavior that Router relies on, but without adding a special case logic into defer.
