Firework Trail Fades At the End/Back Particles

When using this command:

/summon FireworksRocketEntity ~ ~1 ~ {LifeTime:0,FireworksItem:{id:fireworks,Count:1,tag:{Fireworks:{Explosions:[
{Type:0,Flicker:0,Trail:1,Colors:[16725558],FadeColors:[255900]}
]}}}}

No matter the Type, all the trails that are considered "last" will only fade colours. See screenshot below.
