Android onStop() not being called when starting a new activity in multi window mode

I am trying Android N multi window feature and I have found myself confused when starting a new activity. The problem is that when I start a new Activity, the onStop() callback is not being fired and when I press the back button from this new activity to return to the previous one, the previous one's onStart() callback is not being fired either.

Does anyone know what is happening?

--- Edited

It seems like that ActivityOptionsCompat.makeSceneTransitionAnimation has something to do with it.

    If you call another app in multi window mode, your application is still "partially visible", so onPause() is being called, but onStop() not.

    At restart it's the same: onResume() is being called, but onStart() isn't.
