Steps to Reproduce:

1 Summon 1 zombified piglin in creative either by command or spawn egg

2 Use the following command

/execute as @e[type=minecraft:zombified_piglin] run summon zombified_piglin ~ ~ ~ {CanPickUpLoot:1b,CanBreakDoors:1b,active_effects:[

{id:"minecraft:speed",amplifier:4b,duration:-1}

]}

Observed Results:

The speed of the zombified piglin is the same as a zombified piglin without speed

If you use /effect give @e[type=zombified_piglin] speed infinite 1 true, then the zombified piglins will move faster.

 

Expected Results:

The speed of the zombified piglins summoned with the execute command should be faster than those summoned by a spawn egg.
