Sulfur Cube bucketing ignores cancellation PlayerInteractAtEntityEvent

Expected behavior

Sulfur cube doesn't disappear if PlayerInteractAtEntityEvent cancelled, Bucket in player's hand remains empty.

Observed/Actual behavior

Bucket remains empty, sulfur cube no longer exists in the world

Steps/models to reproduce

1. Install a plugin that has this:

@EventHandler(priority = EventPriority.LOWEST, ignoreCancelled = false)
public void onPlayerInteractAtEntityEvent(PlayerInteractAtEntityEvent event) {
    event.setCancelled(true);
}

@EventHandler(priority = EventPriority.MONITOR, ignoreCancelled = false)
public void onPlayerInteractAtEntityEventMonitor(PlayerInteractAtEntityEvent event) {
    getLogger().info(String.format("PlayerInteractAtEntityEvent %s: %b", event.getRightClicked(), event.isCancelled()));
}

@EventHandler(priority = EventPriority.MONITOR, ignoreCancelled = false)
public void onPlayerBucketEntityEvent(PlayerBucketEntityEvent event) {
    getLogger().info(String.format("PlayerBucketEntityEvent %s: %b", event.getEntity(), event.isCancelled()));
}

2. Start server and spawn some sulfur cubes.
3. Try to bucket sulfur cube

Other

Based on discord paper-help discussion, sulfur cube disappears only on client side and would be visible after rejoining server

Reproduce the issue with a plugin that cancels PlayerInteractAtEntityEvent, using the listed sulfur-cube and bucket steps while monitoring both events. Trace the interaction and cancellation flow; done means a cancelled interaction leaves the sulfur cube present and the bucket state correct, including after reconnecting.
