I have a same problem.
Internally, NavController#navigateUp() calls popBackStack().
And popBackStack() calls popBackStack(currentDestination.id, inclusive=true).
public boolean popBackStack() {
if (mBackStack.isEmpty()) {
// Nothing to pop if the back stack is empty
return false;
}
// Pop just the current destination off the stack
return popBackStack(getCurrentDestination().getId(), true); <--- this is cause.
}
So I think,
this problem can't be fixed without navigation cmpt. modification. :(

Description
Component used: Fragment
Allow developers to detect the usage of retained fragments.
This would hook into calls to
setRetainInstance(true)and apply the appropriate penalties if this detection was enabled.
