I have tried to use a invulnerable, inverted, invisible slimes in snapshot to stack a MinecartCommandBlock but they act as normal slimes! Heres the command. Try it in 1.7 (where it functions normally) and than in snapshots!
Command: summon MinecartCommandBlock ~3 ~ ~ {Command:test,Riding:{id:Slime,Size:-2,Invulnerable:1,ActiveEffects:[{Id:14,Amplifier:-1,Duration:200000}],Riding:{id:Slime,Size:-2,Invulnerable:1,ActiveEffects:[{Id:14,Amplifier:-1,Duration:200000}],Riding:{id:Slime,Size:-2,Invulnerable:1,ActiveEffects:[{Id:14,Amplifier:-1,Duration:200000}],Riding:{id:Slime,Size:-2,Invulnerable:1,ActiveEffects:[{Id:14,Amplifier:-1,Duration:200000}],Riding:{id:Slime,Size:-2,Invulnerable:1,ActiveEffects:[{Id:14,Amplifier:-1,Duration:200000}],Riding:{id:Slime,Size:-2,Invulnerable:1,ActiveEffects:[{Id:14,Amplifier:-1,Duration:200000}],Riding:{id:Zombie,CustomName:Test,CustomNameVisible:1,Equipment:[{},{id:301},{id:300},{id:299},{id:397,Damage:3,tag:{SkullOwner:Srdtrk}}],Attributes:[{Name:generic.followRange,Base:0,Modifiers:[]}]}}}}}}}}

They were crashy, conceptually broken and not intended. This was a bug fix, we will not be reverting it.
Confirmed. Slimes that have a negative Size value will instead have their Size tag defaulted to 0, even when labeling the tag-type as integer.
