Villagers do not always close doors after using them

While playing the most recent version (ver. 1.19.3), I noticed that Villagers would often use a door to enter or exit a structure, but they would not close the door afterwards. My guess from watching is that they do not close the door about 30% to 50% of the time. This, of course, leaves them very vulnerable to Zombies when the Villager goes inside to sleep.
