MC-202607 is still reproducible. It might simply happen less often.
How to reproduce
/fill ~ ~5 ~ ~-1 ~5 ~3 minecraft:oak_planks
/setblock ~1 ~6 ~2 minecraft:white_bed[facing=south,occupied=false,part=foot]
/setblock ~1 ~6 ~3 minecraft:white_bed[facing=south,occupied=false,part=head]
/setblock ~-2 ~11 ~ minecraft:oak_fence
Tame and leash a cat
Attach the lead to the fence
/time set midnight
Sleep
Repeat the sleeping process several times
Expected result
The cat would never get off the lead.
Observed result
Sometimes the cat escapes the lead. This can be annoying, particularly when you're in a house where your bed is on the second floor. The smaller the floor area, the more likely the cat is to escape the lead. Even with a larger floor, the cat can still manage to get off the lead.
