Link to the code that reproduces this issue

To Reproduce

1-npm run dev
2- navigate to /post/[id]

Current vs. Expected behavior

after step 2 you can see that is show the data directly and if i added a sleep function of 5 second it will wait all that time and not showing a suspense fallback
I expect to the the suspense fallback just like in other route (note: suspense is not working only on a nested route, folder inside folder)

Additional context

This bug seems to happen only in a nested route, as the same component or page will work very well in the main route, I tested the same component (Post) in in a dynamic route and it's not working but works on the main page.js
