Summary

Same issue of MC-266155 (Except for vindicators wasn't open)

Villagers can open copper doors as if they were wooden doors.

Addons/Resource packs: No

Attachments: Yes

Experiment features: Yes

Verified builds: 1.20.50.22 Preview

Steps to reproduce

1. Create a new world and use the 1.21 experimental toggle 

2. Make an enclosed space with only one exit

3. Place a copper door closing that exit

4. Spawn a villager inside the enclosed space

Observed result

The villager will open and close the door without any issue at all.

Expected behavior

The villager should not be able to open the copper door, as they should only be able to open wooden doors.

Note: this would even be useful as copper doors would be the first door that can be opened by players but not by villagers.
