This actually has nothing to do with NavHostFragment, but is the behavior of NavController's setGraph().
When you call navController.setGraph(R.navigation.navigation_graph), it stores that ID and will restore that ID automatically.
If you were to instead use:
NavInflater navInflater = new NavInflater(this, navController.getNavigatorProvider());
navController.setGraph(navInflater.inflate(R.navigation.navigation_graph));
Then NavController would not restore the graph itself and the call to restoreState() you point out would only restore the back stack state, etc. but would wait for you to call setGraph again.
You're right that the inconsistency between the two setGraph methods is concerning. We'll take a look.

Turns out, we already had a tracking bug for this issue, will follow up on that other one.

Thank you for promptly replying to my report. You are right that the issue you've just mentioned is similar to mine. I shall continue observing the progress over there.
Description
Version used: 2.1.0-alpha03
Devices/Android versions reproduced on: Any
When I show dialog from any fragment in Navigation Component, background fragment will create a back button in it's toolbar. Is there any option to not show back button in background fragment when dialog is popped. Or any possible workaround?
If this is a bug in the library, we would appreciate if you could attach:
- Sample project to trigger the issue.
- A screenrecord or screenshots showing the issue (if UI related).
