Mobs and items become invisible when dying

When i used the new feature in 15w38b (with undead horsemen) i got killed, and i have respawned, all entities were invisible.

Steps to reproduce:
1. Make a world
(superflat will be the best option, gamemode set to creative. CHEATS NEED TO BE ENABLED!!!)
2. Use this command:

/summon EntityHorse ~ ~ ~10 {SkeletonTrap:1b}

and get close to the Horse

3. Set your spawnpoint and set the gamerule 'keepInventory = true' (+optional+)
4. Do /kill
5. Respawn
6. All entities (+items) that didn't spawn right after you respawned are invisible.
