Player Heads do not render in inventory or when equipped

When giving a player a Players head using the /summon command, the Head does not render the specified player's skin although it is named correctly. When the head is placed the specified player's skin appears. Also when the Player head is equipped as a helmet, HUD elements (Items/blocks, armour slot guides) to disappear and the inventory slot highlight is moved and blown out of proportion. Along with this the Player Head does not render over the wearing players skin.
