Bug with 1.10 spawn eggs [creative]

So... the list is long. Let's go.
(For all that is below, you must press the button "select the block" (pick block) targeting the monster.)

• entity.zombieHorse.name | entity.skeletonHorse.name | entity.mule.name | entity.donkey.name egg is given as normal horse.

• Elder guardian egg is given as normal guardian.

• Cat egg is given as ozelot and the cat is not tamed (we can't right click on the cats)

• Husk egg is given as normal zombie.

• Wither skeleton | Stray egg is given as normal skeleton.

Again, sorry for my English, I'm French so is hard for me :x
