What is the current behavior?

The initial app start is not calling the core modules' __onLiveSync method as it expects that the changes are already applied. However, the HMR updates and the app start are asynchronous and when the app starts before the Hot Updates, the core modules are never updated.

What is the new behavior?

We always call the core modules' __onLiveSync in order to ensure that the hot updates will affect the app state.
