if i summon mobs from the build height, some mobs, mostly the undead ones, don't take fall damage if they land on buttons or hoppers.
Steps to reproduce:
place down a hopper, button, lever, or slab.
Summon a mob (zombie or skeleton) at a height that they will die from fall damage.
expected result- mob will take fall damage and die.

I can reproduce this during the day, but not at night. That's because undead monsters burn during the day, and being on fire can cause fall damage to be ignored. We are already tracking that issue at MCPE-37680.
