The Elytra Fails To Fly In 16w07a... Sad Day. Sad Week. Sad until this is fixed.

How i discovered this? I learned that elytra textures are replaced with your cape, And i read how to get a cape a while ago, Realms. Turns out i misread it. and thought that i had it. tested it out.. and not so shockingly, i did not have a cape. I Still played around with the Elytra. I Jumped off of my spaceship build. and BAM!!! I Fell. (I Did not Glide. Just plain FELL)

Please Fix This!
