NoAI-mob-passenger behavior in a boat (head not fixed)

How to reproduce

/summon minecraft:boat ~ ~ ~ {CustomName:"\"boot\"",Passengers:[{id:zombie,NoAI:1,CustomName:"\"bootsman\""}]}

At first the Zombie looks straightforward (picture 1) but as soon as you make a turn with the boat the head of the Zombie turns 90 degrees and stays fixed this way (picture 2). Expected and desired behavior would be that the head always looks forward.
