Lose items when picking up stuff from a broken chest in Multiplayer

When completely filling a large chest with an item, then breaking it, then placing the items in another double chest, a stack (64) of the item is lost.

For example, filling a large chest with apples, then breaking it so you pick the items up again (2 people needed to pick up all items), then placing the items back in the chest, there are some missing.

This happens on Multiplayer minecraft (hosted, not LAN), and can be replicated every time.

However, when you close the chest, then open it again, MOST of the items are back again. This was the case for us, as we closed the chest (missing one stack), then opened it again and there was 57 apples, so there were now only 8 missing.
