BlockExpEvent does not fire when using a grindstone

[KabanFriends]

Expected behavior

When using a grindstone to remove enchantments from an item, it should fire BlockExpEvent as the grindstone drops experience orbs.

Observed/Actual behavior

When using a grindstone to remove enchantments from an item, the server does not fire BlockExpEvent.

Steps/models to reproduce

1. Code a test plugin that listens for BlockExpEvent

@EventHandler
public void onBlockExp(BlockExpEvent event) {
    BlockPosition pos = event.getBlock().getLocation().toBlock();
    System.out.println("Event at " + pos);
}

2. Join the server and use a grindstone
3. See that the test code is not triggered
