🐛 [firebase_messaging] initialMessage should be kept, even if it doesn't contain [Notification] part #12370

I'm making a Flutter app that includes in-app messaging, and I'm managing my push notifications with Firebase.
I also have non-message notifications that are sent via Firebase too.

I need a different look for message notifications (MessagingStyleInformation), so I handle them in background and terminated state by not sending Notification part in a RemoteMessage from backend, and then using a global function in my app to handle showing appropriate notification style. But there is a problem, now when I click on the push notification for chat and my app is in terminated state, it cannot redirect to a chat screen because FirebaseMessaging.instance.getInitialMessage() returns null.

This is the code in my home screen:

It works fine with my non-chat push notifications (getInitialMessage will return an actual RemoteMessage that came, because it contains Notification part) , but as I mentioned before, it doesn't work with message push notifications.

Can this condition for Notification part be removed, so that Firebase Messaging plugin can remember all remote messages that came?
