Unlike horses, even low heights will inflict fall damage onto skeleton horses.
steps to recreate:
Ride a skeleton horse or spawn one in
Ride it off the standard height for player fall damage or higher OR push it off a block
This can ultimately result in them being killed by the damage. This should be considered a bug, if anything unintentional

I could not reproduce, and I have a feeling this is connected to lag or it is a specific issue with granting damage, like MCPE-154779 or similar bugs. Does this reproduce on one world, or all worlds you have?
