With the new Minecraft 1.11. I didn't think this is normal. But I was testing on my Spigot 1.11 server when I pulled up dragon head in the creative inventory, it shows it backwards (see attachment below). Then, when I opened a chest with the head in my hand, it kind of engulfs the screen with "inside" of the skull, which I thought it looks weird. I tested on the single world servers, and it's still the same issue. It happens with the other skulls too. So, if this was set on purpose, please let me know. Thanks!

P.S. I know 1.10.2 has the skulls facing the front way (skull facing you). Sorry if the dragon head was hard to see...
