Using the command
/summon magma_cube ~ ~1 ~ {Silent:1b,Passengers:[{id:"minecraft:zombie",Silent:1b,Invulnerable:1b,IsBaby:1b,ArmorItems:[{},{},{id:"minecraft:diamond_chestplate",count:1},{}],active_effects:[{id:"minecraft:invisibility",amplifier:0,duration:200000,show_particles:0b,show_icon:0b,ambient:0b}]}],active_effects:[{id:"minecraft:invisibility",amplifier:0,duration:200000,show_particles:0b,show_icon:0b,ambient:0b}]}
On a commandblock at night summon a baby zombie riding a magma cube (small for this example). Both baby zombie and magma cube individually chase for the player but while the first is riding the second they got no interest in the player and they just roam randomly.
Thank you

This one will do it. I simply pasted the command i was using while playing in creative, maybe I just copied it wrong. Anyway this one right here should work. Otherwise let me know what error gives to you or just summon a zombie on a magma cube
Thank you for your report!

Can confirm, although the command in the description seems to be broken
