[v5] bottomTabNavigator: on tabPress -> sharedElementStackNavigator doesn‘t navigate to initialRoute

I nested my _SharedElementStackNavigator_ in a _BottomTabNavigator_. If I click on the corresponding Icon in the _BottomTabNavigator_ the _TabNavigator_ navigates to the _SharedElementStackNavigator_ (if it isn't already open), but the _popToTop_ action of the _SharedElementStackNavigator_ isn't fired. If I replace the _createSharedElementStackNavigator_ with the normal _createStackNavigator_ everything works fine, but, of course, the Animation is lost.

So I have the problem, that I don't get navigated to the initialRoute of the _SharedElementStackNavigator_, if I press on the corresponding Icon in the TabBar, although that's normally standard.

Im am using the v5-navigation.

How do I solve this issue? Or is a fix planned?

Start by reproducing the nested SharedElementStackNavigator inside a BottomTabNavigator with React Navigation v5, then compare tab-press behavior with a normal stack navigator. Done means pressing the corresponding tab navigates to the stack's initial route by triggering the expected popToTop behavior without losing the shared-element animation.
