Zombie villagers do not attack villagers.

This is confirmed on the Xbox One version 1.2.13.54. I found a zombie spawner and made a small grinder. I made a way to let out villager zombies into a chamber for conversions to trade. In the event of trying to get rid of a "unfair trader" I let multiple other villager zombies in. I was able to heal 2 more while they were in with the villager. Definitely odd and funny but but not working as intended.

It doesn't do it on pocket either.

Thank you for your report!
