Splitscreen players no longer connecting to the same Player

Since the latest update (vibrant visuals), players connecting to realms via splitscreen are not able to access their inventories from before the update. It seems that they are using a sub-account of the first player as other users will see “Player1 (2) connected” rather than “Player2 (connected)”.

This means that when connecting to realms, only the first player will get the correct items, where previously it would not matter who the first player was.

Expected: The second players should connnect the the same user account they did in previous versions, where it is based on their own username.
