Sorry for the necro-post but this says it's still waiting confirmation - has occurred for me in Java 1.16.4. (I came here because I noticed this issue for the first time but it's the first time in a long time I've laid a bed against a wall.) While laying in bed, stone brick along right (east) side, iron bars behind head, rest is empty. Bed is on stone brick, 1 block high empty above bed.
