Snow Golems get affected by freezing effect

Snow Golems freeze to death in powdered snow

What I expected to happen was...:
Since they are made of snow, shouldn't they be immune to freeze damage?

To me, that counts as an inconsistency or a bug

What actually happened was...:
They die lol

Steps to Reproduce:
1. summon a snow golem
2. put  them in powdered snow
3. they cease to live lol
