SuperUser uploads avatar for User1 and start to get notification about reaction on it

Hello.
1) SuperUser upload avatar and cover to User1
2) User2 react to User1’s avatar and cover
Result: SuperUser get notification about this reactions.
User1 doesn’t get any notification.
Expected Result: User1 should get notofication because it's his avatar.

I suppose the same with commenting.

Or it works OK because avatar's author is SUperUser now?

Thanks.
