### Godot version

v4.0.beta13.official [caacade56] - v4.0.beta16.official [518b9e580]

### System information

Windows 10

### Issue description

Since Beta13 the inspector shows a duplicate "override_pose" property on the BoneAttachment3D node. Toggling one property toggles them both.

Perhaps related to the work done in #71137?
