Small slimes don't hurt the player

I spawned a small slime in creative mode and it didn't hurt me in survival mode. NOTE: I SEARCHED FOR THIS ISSUE AND IT WASN'T REPORTED

What I expected to happen was...:
The small slime would deal at least 1 point of damage

What actually happened was...:
The small slime didn't deal any damage

Steps to Reproduce:
1. Go to creative mode with cheats on and get a slime spawn
2. Spawn several slimes until you get a small one (or just kill the big/medium slimes)
3. Go to survival mode (with /gamemode 1)
4. Enjoy small slimes not hurting you
