Summoning a creeper using this command cause it to not have the invisibility effect applied to it, so when it is summon it is still visible.

/summon Creeper ~ ~1 ~ {Fuse:0,ignited:1b,ActiveEffects:[{Id:14,Amplifier:0,Duration:10,ShowParticles:0b}]}

Don't know if this issue has already been raised, wasn't able to find an issue outlining this and this issue has been present for over a year
