Can't put an Elytra in a player's chest using /replaceitem command.

I tried to make a player wear an Elytra (the new wings) in the latest snapshot using the /replaceitem command in a Command Block... Didn't work.

Maybe it has to do with the fact that the Elytra is in the Transportation section in the Creative Inventory, so it is not considered an item that can be worn by a player?
