I searched and didn't see this. On my '12 JKR, the glove box allows things, like keys, to fall down behind the back panel of the box, into the bowels of the dash. If something is missing (like keys your dealer said were put into the glove box - long story), check down behind the box. When unlocked, it's easy to pull out the box from its hinges, and reach down behind it to see if anything has found its way down there.
With the open space at the top, back of the glove box, I'm sure that about half the Jeeps out there with this design have swallowed otherwise "missing" items.
