When muting a player, if that player starts whispering to you, you will still be notified that they are trying to whisper to you.
Expected behavior: Muting a player should completely stop communication from them to you, in any way possible.
The “You are now privately chatting with Player1.” message should not appear because Player1 is muted - either caused by user input, or from the game code (silencing shadowbanned users).
