Mob effect particles are black when using ShowParticles:0b and creepers not invisible

Running this command:

/summon Creeper ~0 ~1 ~0 {Fuse:0,ignited:1,ActiveEffects:[{Id:14,Duration:999999,Ambient:1,ShowParticles:0b}]}

Will cause a creeper to be spawned and immediately explode but it leaves behind black particle effects when you have the ShowParticles:0b tag, without the ShowParticles tag it correctly displays the grey particles.

A side note, since its related to the same command, the creeper also is visible for a few frames even though it should be invisible from the potion effect, if you adjust the Fuse time to 2-3 then the creeper doesn't explode.
