When using the summon command to create a firework the fireworks does not register any internal data about explosions, I've tried multiple variations of formats for the command and none result in a firework that explodes like they did before 24w09a
command used in 1.20.4: /summon minecraft:firework_rocket ~ ~0.1 ~ {Silent:1b,Motion:[0.0,0.0,0.0],ShotAtAngle:1,LifeTime:0,FireworksItem:{id:"firework_rocket",Count:1,tag:{Fireworks:{Flight:1,Explosions:[{Type:1,Flicker:0,Trail:0,Colors:[I;65535]}]}}}}
