Confirmed in 20w22a. I'd also like to clarify that this affects all entities, not just players.
I'm not sure just how different the Forge library is from Minecraft's actual code, but looking at Forge public boolean canBeRiddenInWater() { return true; }
can be found in the SkeletonHorseEntity class but not the ZombieHorseEntity class. Simple fix?
