Items spawned in chest with /setblock disappear when a hopper is used to remove the items from the chest

When creating a chest with an item using the the /setblock command:

/setblock ~0 ~0 ~2 minecraft:chest 0 replace {Items:[{id:274,count:1}]}

If I use a hopper below the chest to remove the item, the item disappears entirely and is no longer in the chest or the hopper.
