Always hide username not working in certains conditions

[dadodasyra]

Issue description

• Expected result: The player username should be hidden
• Actual result: When some conditions are met the username is visible through blocks

Steps to reproduce the issue

1. Two players connects
2. One player (player A) triggers something which will calls this on himself

$sender->setNameTagAlwaysVisible(false);
$sender->setNameTagVisible(false);

3. The other player (player B) will still be able to see its username.

It does work if the player B disconnects and reconnects (the player needs to login after the hidden username one).

• Using JIT: no
• Server OS: Debian 11 (or 12 dk)

  Tried with just the example plugin + devtools and yes.
• If the issue is not reproducible without plugins:
  • Can you provide sample, minimal reproducing code for the issue? If so, paste it in the bottom section

The more I think about it the more I'm asking myself if it's not a client side bug ? It definitely needs some investigation
