Horses with jump boost take fall damage

The bug

When mobs or the player have jump boost and they fall as high as they jumped they won't take fall damage. This is not the case for horses which take fall damage.

How to reproduce

1. Summon a horse

   /summon horse ~ ~ ~ {Tame:1b,SaddleItem:{id:"saddle",Count:1b}}
   

2. Give it jump boost

   /effect give @e[type=horse] jump_boost 10000 10
   

3. Reopen the world (due to MC-121788)
4. Mount the horse and jump
