Zombie horses are undead mobs, and like all other undead mobs (zombies, skeletons, zombified piglins, zombie villagers, strays, bogged, husks, zoglins, skeleton horses) they should sink in water and also keep their mount riding underwater like skeleton horses do
Steps to produce: spawn any hostile mob (zombie, skeleton, zombified piglin, zombie villager, stray, bogged, husk, zoglin, skeleton horse) in water thats at least 2 blocks deep, then do the same with a zombie horse
Expected behavior: all the hostile mobs should sink in the water including the zombie horse which is undead
What actually happens: all hostile mobs sink in the water except for the zombie horse
