In the last snapshot, clearing player's items creates ghost items.

What I was expecting to happen:

Clearing a player clears his items.

What happened:

It creates ghost items. You can move them in your inventory if you're in creative, you can right click on it and it plays the animation - even if nothing happen (for example, you can try to drink a potion, the animation will play BUT you won't receive the effect.)
You can equip fantom armors ; you can break blocks in creative with the ghost sword (even if it won't make the sound, wich is weird).

Steps to reproduce

● First, create a flat new world.
● Give yourself a repeating command block :

/give @p minecraft:repeating_command_block

● Enter the following command in the command block :

clear @a

● Change the command block settings to : Always Active
● Now leave the command block & take items from your inventory.

A message should display (your inventory was cleared) but the item is still here, as a ghost item.
