No stray, wither skeleton, mule, donkey, skeleton/zombie horse, cat, elder guardian or husk spawn eggs, entity variant spawn eggs removed

Hello! Minecraft 1.10 Pre-Release 2 has released 5 minutes ago as of writing this and it states that new sounds for mobs were added so I quickly jumped into creative mode and realise that the Mule, Donkey, Stray, Elder Guardian, Wither Skeleton and the Husk spawn eggs are missing. I don't know if this is intentional or not. Thank You for reading this and keep up the good work!
