How to prevent BottomSheetDialogFragment from dismissing after a navigation to another fragment?

I am using NavigationComponent on my App.

I have an specific flow where after a click on a button of BottomSheetDialogFragment the app should navigate to another fragment. But when that Fragment is popped I need to navigate back to the previous BottomSheetDialogFragment.

For some reason the BottomSheetDialogFragment is being dismissed automatically.

Frag A : click on a button  
Frag A -> Dialog B : click on a button  
Frag A -> Dialog B -> Frag C : pop Frag C from the stack  
Frag A : Dialog B was automatically dismissed =;/  

How can one prevent that dismissing?

Q: Why do I need the BottomSheetDialogFragment not dismissed?
A: I listen to the result of the opened fragment through a LiveData. Due to the dismissing of the BottomSheetDialogFragment it never receives the result.

This is not possible. Dialog destinations implement the FloatingWindow interface which states:

Destinations that implement this interface will automatically be popped off the back stack when you navigate to a new destination.

So it is expected that dialog destinations are automatically popped off the back stack when you navigate to a <fragment> destination. This is not the case when navigating between multiple dialog destinations (those can be stacked on top of one another).

This issue explains a bit more about the limitations here, namely that:

1. Dialogs are separate windows that always sit above your activity's window. This means that the dialog will continue to intercept the system back button no matter what state the underlying FragmentManager is in or what FragmentTransactions you do.

2. Operations on the fragment container (i.e., your normal destinations) don't affect dialog fragments. Same if you do FragmentTransactions on a nested FragmentManager.

So once you navigate to your <fragment> destination, the only way for the system back button to actually work is for all floating windows to be popped (otherwise they would intercept the back button before anything else) as those windows are always floating above the content.

This isn't a limitation imposed by the Navigation Component - the same issues apply to any usages of BottomSheetDialogFragment regarding the Fragment back stack and the system back button.
