Invisible Charged Creepers render incorrectly

When inflicting the Invisibility effect onto a Charged Creeper, the creeper becomes completely invisible, when the base model should only be invisible, and the "charged" aura should remain visible.

Steps to reproduce:

Summon a charged creeper. (In this instance, I used 

1. /summon creeper ~ ~ ~ minecraft:become_charged

   ) 

2. Inflict it with Invisibility

Expected Results:

The creeper is invisible, but its aura remains visible.

Actual Results:

The creeper is invisible entirely, and not even its aura is visible.
