Entities don't render properly when next to invisible spider, charged creeper, or wither boss with armor

What I expected to happen:

Entities next to the invisible spider to render properly

What actually happened:

That entity didn't render properly

How to reproduce (Spider):

1. Spawn a spider
2. Throw splash potion of invisibility on the spider
3. Spawn any entity next to the spider
4. Notice how the entity looks weird

How to reproduce (Creeper):

1. Spawn a creeper
2. Make sure entity shadows are set to off in the video settings. (Options... -> Video Settings... -> Entity Shadows)
3. use

/entitydata @e[type=creeper,c=1] {powered:1b}

4. Spawn any entity next to the creeper
5. Notice how the entity looks weird

How to reproduce (Wither):

1. use

/summon wither ~ ~ ~ {Health:0.1f,NoAI:1b,ActiveEffects:[{Id:14,Amplifier:1b,Duration:10000}]}

2. Spawn any entity next to the wither
3. Notice how the entity looks weird
Probably invalid since bosses can no longer have effects without using commands

Notes:

• If the spider/creeper dies, moves far enough, or is no longer invisible/charged,the entity starts rendering normally.
• Other Entities can be seen through the bugged entity
• This cannot be used to see entities through wall as shown in pictures 7 and 8.
• The creeper one doesn't usually happen unless Video Settings: Entity Shadows is off, because shadows reset the depth mask.
