I thought that when I summoned a skeleton wearing an ocelot head, it would spawn wearing one.

The skeleton was spawned successfully, but the head it was wearing was NOT an ocelot head. Instead, Steve's head appeared.

Steps to Reproduce:
1. Get a command block
2. Set the difficulty to easy, normal, or hardcore
3. Type in the command block the following:
/summon Skeleton ~ ~1 ~ {Equipment:[{},{},{},{},{id:397,Damage:3,tag:{SkullOwner:MHF_Ocelot}}]}
4. Give the command block a redstone signal

It happens with any head I try on any mob that can wear heads, but it does not want to work. I have tried setting the drop chance of the head to 100% then killed the mob. When I placed the head on the ground, the proper skin showed up, but I need the proper skin spawned onto the mob.
