Issue

When starting an activity with an implicit deeplink and then navigating to the start destination of the root nav graph, the NavHost shows the target destination for a short moment and then turns white / blank and the backstack is empty. This even happens when navigating to other destinations first.

My nested NavGraph contains these destinations:

Root 
└─── navigation Main
    ├─── navigation Settings
    │   └─── composable Settings.Screen
    ├─── navigation Home
    │   └─── composable Home.Screen
    └─── navigation FavoritesOverview
        ├─── navigation FavoritesDetail
        │   └─── composable FavoritesDetail.Screen
        └─── composable FavoritesOverview.Screen

The deeplink is launched by restarting the activity like this:

val uri = deepLink?.toUri()
val intent = Intent(Intent.ACTION_VIEW, uri, context, MainActivity::class.java)
intent.flags = Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK
context.startActivity(intent)

and handling the deeplink via

navController.handleDeepLink(intent)

Then the NavHost becomes blank when navigating to Home with popUpTo:

navController.navigate(Home) {
    popUpTo<Main> {
        saveState = true
    }
    restoreState = true
    launchSingleTop = true
}

Workaround

Navigating twice, manually or programmatically, works around this issue.
