[MCPE-16931] Zombie Horses & Skeleton Horses gradually lose health & die from nothing

After spawning in a Zombie Horse and a Skeleton Horse, both seem to die randomly after some time has passed. Neither of them were damaged by any means.

Edit by @unknown: After some testing, it looks like the skeleton/zombie horses slowly lose health over time for no apparent reason, before finally dying. They make NO death sound when they die and drop no items. The cause of this bug is that horses gradually regenerate health over time, through the "healing" effect. But since zombie horses & skeleton horses are undead mobs, this healing effect actually damages them.

I can't reproduce this using spawn eggs in creative single player on my Samsung Galaxy S6 (SM-G920W8), Android 6.0.1 MCPE 0.15.90.2.

Please explain how you spawn the zombie/skeleton horses and if the game mode is different.

In a creative flat world, I used spawn eggs to spawn one zombie horse and one skeleton horse. I then watched them for 5 minutes, moving only to keep them both in view at all times. I didn't see either of them take damage or act like they had taken damage. @unknown how many of these did you spawn? Did you build/dig anything to confine them in the creative flat world? Did you interact with them? Did you let your device go to sleep and turn it back on? I presume you did not use /summon to spawn the horses. Ah.... nevermind, I left the game running as I typed all of that <<< and as I typed, the Zombie horse died...

CONFIRMED on Samsung Galaxy S6 (SM-G920W8), Android 6.0.1

Steps to reproduce: spawn a zombie horse or a skeleton horse from a spawn egg in a creative flat single player world. Follow it around for a while (first one died about 6-7 minutes, second took about 12, third about 6-7 happened during daytime and night time all in the same creative flat world). They will eventually die, as far as I can tell without ever showing or sounding that it was getting hurt. Each turned red, then fell over and there was the puff of smoke like dying, just no sound.

Spawning 4 of each zombie and skeleton horses at the same time in a fenced in area, each still died at random time intervals (i.e. they didn't all die at the same time, so there isn't something slowly hurting all of them the same).

I tested one more time, creating a fenced-in area of a few chunks in size in a new single player creative flat world. In it, I spawned 3 each of horse, donkey, mule, skeleton horse, zombie horse, zombie pigman and creeper in quick succession. I watched and waited not letting my device sleep. After about 10 minutes, all 3 skeleton horse and zombie horse had died. None of the other mobs died.

Confirmed to still be happening as of 0.16.2 & 1.0.0.2. I've also noticed that when they die randomly, they don't make any death sounds and they don't drop anything.

Also, the zombie/skeleton horses will die irregardless of whether or not they are under a roof or not, so they're definitely not taking fire damage somehow or something like that. (And again, their deaths are silent.)

Is this still happening in 1.0.0? (It's also worth mentioning that skeleton horse traps don't spawn in thunderstorms, no matter the difficulty).

@unknown Are you sure skeleton horse traps aren't spawning? In 1.0.0 (or was it 0.16, I can't remember...) skeleton horse traps were made a whole lot more rare than they used to be. It took me a really long time testing to get one to spawn, last time I checked during the 1.0.0 beta... are you absolutely certain they aren't spawning in 1.0.0 at all?

Revised title & description to contain more info.

It looks like do they spawn, but they're incredibly rare 😞
