The BlockRedstoneEvent is not called when fence gates are opened/closed by redstone power. This goes against the expectation because for doors blocks this event is called (albeit for only the half that received power)

Steps to reproduce:

1. Put the following plugin your server (now included in the attachments):

   package com.example;
   
   import org.bukkit.event.EventHandler;
   import org.bukkit.event.Listener;
   import org.bukkit.event.block.BlockRedstoneEvent;
   import org.bukkit.plugin.java.JavaPlugin;
   
   public class TestPlugin extends JavaPlugin implements Listener {
   
       @Override
       public void onEnable() {
           getServer().getPluginManager().registerEvents(this, this);
       }
   
       @EventHandler
       public void onBlockRedstoneEvent(BlockRedstoneEvent event) {
           getLogger().info(event.getBlock().getType().name());
       }
   
   }
   

    

1. Start the server and build a setup such as in my attachment.

1. Flick the lever and verify through the console/logs that the only materials for which the event is called are LEVER, REDSTONE_WIRE and OAK_DOOR. The OAK_FENCE_GATE is missing.
