The Bug:

The saddles of horses, mules, and donkeys along with the chests of mules and donkeys, flash red when the mob is damaged.

The saddles/chests on these mobs should not flash red because these objects aren't taking damage; only the mob is.

Steps to Reproduce:

1. Summon a horse, donkey, and mule by using the commands provided below.

   /summon minecraft:horse ~-3 ~ ~-3 {NoAI:1b,SaddleItem:{id:"minecraft:saddle",Count:1b}}

   /summon minecraft:donkey ~ ~ ~-3 {NoAI:1b,ChestedHorse:1b,SaddleItem:{id:"minecraft:saddle",Count:1b}}

   /summon minecraft:mule ~3 ~ ~-3 {NoAI:1b,ChestedHorse:1b,SaddleItem:{id:"minecraft:saddle",Count:1b}}

2. Attack each of the mobs and as you do this, watch the mobs' saddles/chests closely.
3. Take note as to whether or not the saddles/chests flash red.

Observed Behavior:

The saddles/chests flash red.

Expected Behavior:

The saddles/chests would not flash red.
