我发现在使用嵌套的StackNavigators时，react-navigation（v1.5.11） Headers 中的默认后退按钮会返回到之前的StackNavigator . 例如，请考虑以下事项：

The first level StackNavigator (used within a TabNavigator)

export const NotebookStack = StackNavigator({
  NotebookMain: {
    screen: NotebookContainer,
    navigationOptions: {
      title: 'My Notebook'
    },
  UserFavorites: {
    screen: FavoritesStack,
    navigationOptions: {
      tabBarVisible: false,
      swipeEnabled: false,
      title: 'My Favorites',
      headerTitleStyle: {
        fontSize: 24,
        fontFamily: 'WorkSansLight',
        fontWeight: '200',
      }
    }
  }
});

FavoritesStack used in the above first level StackNavigator

export const FavoritesStack = StackNavigator({
  FavoritesSearch: {
    screen: FavoritesSearchContainer
  },
  FavoritesFilters: {
    screen: FavoritesFiltersSlim
  }
}, { headerMode: 'none' });

当导航到“FavoritesFilter”路线并按下手机的后退按钮时，它会导航回“FavoritesSearch”路线 . 但是，当按下 Headers 中的默认后退图标时，它会导航回上一个堆栈中的“NotebookMain” .

根据手机的后退按钮与默认 Headers 的后退图标相比，后备行为的差异是什么？
