When viewed through a Charged Creeper's energy field, mobs (and other entities, as well as Chests and Signs) are completely invisible. Applying Status Effect of Invisibility changes the effect: the energy field will render behind entities. This bug manifests under conditions difficult to determine; orientation and mob species appear to be important.

yes this is still the case. When they are invisible the armor will still show and it will be shown behind chests other mobs. Sometimes this kicks in and works at certain angles though.
