Note: Please see the attached image.

So, you probably know about 1.16.100's "Illuminati" glitch where sleeping villagers can be pushed out of their home beds by the player and start floating away. This may or may not be a duplicate of that, so feel free to mark it as such, but it seems different enough, as the villager in this image is not sleeping at all.
This is my first bug report, at least in a long time, so please be considerate if I'm not doing something correctly. Thank you for reading!
