The bug
Skeleton horse and undead horse that have been spawned from a spawn egg cannot be interacted with in any way.
Expected behavior
Spawning a skeleton horse from a skeleton horse spawn egg will spawn a tamed skeleton horse that you can ride on, open its inventory, put a saddle on it and feed it or an untamed skeleton horse that can be tamed by riding it.
Spawning an undead horse from an undead horse spawn egg will spawn a tamed undead horse that you can ride on, open its inventory, put a saddle on it and feed it or an untamed undead horse that can be tamed by riding it.
What happens
A skeleton horse that spawned from a skeleton horse spawn egg cannot be ridden on, open its inventory, put a saddle on it, be tamed, feed it.
An undead horse that spawned from an undead horse spawn egg cannot be ridden on, open its inventory, put a saddle on it, be tamed, feed it.
