+Subject: [PATCH] Refresh player inventory when cancelling
+ PlayerInteractEntityEvent
+
+When interacting with entities with an item, the client will assume
+the interaction is successful, and update the held item on the
+client. However, if the interaction is cancelled on the server side,
+the client will still mistakenly remove/replace the item in hand.
+
+Examples for this are milking cows with a bucket or dyeing sheep.
+The bucket is replaced with milk and the dye removed from inventory.
+
+Refresh the player inventory when PlayerInteractEntityEvent is
+cancelled to avoid this problem.
