Usernames longer than 16 characters cannot join servers.

So, there is an issue with joining multiplayer servers if you have a username longer than 16 characters, and I have a username that is 18 characters long. Whenever I try to join a server on 1.19.3, it kicks me and gives the error message "Internal Exception: io.netty.handler.codec.EncoderException: String too big (was 18 characters, max 16)". I was wondering if this issue could be fixed since it is really annoying not being able to play multiplayer just because of this bug.
