Villagers can declare a bed forever even if it is not within their reach

Once the villager has appeared with a declared bed, this attribute is not removed and can still be considered his even if it is no longer within his reach. Screenshot with a captivity of villagers below where they cannot have contact with their bed, but it remains theirs, preventing the creation of new villagers.
I would like it to be a duplicate, so I know if you are already working on it. too late for me
