      Description

      When mobs are moving in flowing water in a 1 wide by 2 high tunnel with a solid block above and jump/bob as they move along the water stream, some mob's heads will go into the solid block above them causing suffocation damage. The issue is worsened when there are many mobs in the same area pushing each other.

      Mobs that get damaged:
      Cows
      Baby Cows
      Baby Sheep
      Mooshrooms
      Baby Mooshrooms
      Chickens
      Baby Chickens

      Mobs that do not get damaged:
      Sheep
      Pigs
      Baby Pigs
      Wolves
      Baby Wolves
      Ocelots
      Baby Ocelots
      Rabbits
      Baby Rabbits
      Horses (baby horses don't work right now to test)

      Possibly related to MC-48544 but created new issue as this also affects baby sheep, chickens, and baby chickens. I doubt this "works as intended" when the issue is inconsistent with other mobs.
