Firework rockets travel far less when launched by a dispenser

When shooting a firework from a dispenser, the rocket does not travel as far as it used to.
I love the idea of having it shoot out it's respective sides, and I don't mind that it flies straight either. I just think it need's to have the same amount of distance/height it used to.

To Reproduce

give @s minecraft:firework_rocket{Fireworks: {Flight: 5, Explosions: [{Type: 1, Flicker: 1, Trail: 1, Colors :[I; 8073150, 6719955, 12801229], FadeColors: [I; 14188952, 4312372]}]}} 64

Fire this firework rocket manually, and fire it by a dispenser.
(This command comes from MC-168614)
