Giving a TROPICAL_FISH_BUCKET ItemStack with customized TropicalFishBucketMeta does not actually apply the ItemMeta to the item.

Secondarily to this issue: whilst in creative mode, opening your inventory with a customized TROPICAL_FISH_BUCKET ItemStack will kick you from the server, I assume that once the meta is properly applied to the ItemStack this issue will also be resolved.

Replication Steps, this applies to both:

1. Give a TROPICAL_FISH_BUCKET item with a set pattern, body color, or pattern color.

• • final ItemStack stack = new ItemStack(Material.TROPICAL_FISH_BUCKET);
    final TropicalFishBucketMeta meta = (TropicalFishBucketMeta) stack.getItemMeta();
    
    // This can by a pattern, pattern color, or body color.
    meta.setBodyColor(DyeColor.RED);
    stack.setItemMeta(meta);
    player.getInventory().addItem(stack); 

• • Placing the bucket will randomly place a fish.
  • Or use the provided plugin Jar and execute /test

1. Open your inventory whilst in Creative Mode.
2. You will be disconnected with

• • The error is from a Paper server. I couldn't get any error to thrown in console on a spigot server but the behavior seemingly remains consistent between paper and spigot.
