The bug

As described in title. If you charge the Respawn Anchor block on multiplayer, you can hear the charging sound effect, but other players next to you cannot. This is an exception to almost all other blocks in the game, and so very likely a bug.

How to reproduce

1. Enter a multiplayer game in any gamemode
2. Place a Respawn Anchor
3. Try to charge the Respawn Anchor with another player within a few blocks of you
   →  The charging sound will be played for you, but not the other player
