[haulinh]

Is there an existing issue for this?

• I have searched the existing issues

Summary

I read the code implement layout for the app can't persist page state. So pls implement layout in _app

Why should this be worked on?

Because when navigating between pages, we want to persist page state (input values, scroll position, etc.) for a Single-Page Application (SPA) experience.

@haulinh We have implemented this layout mechanism in our past releases, also we have moved to NextJS App directory in the latest release v0.22-dev. So closing this issue as this out scope now.
