FWIW the steps given in the Spigot bug don't reproduce the bug in vanilla either.

I wonder if MC-144784 being fixed affected this.

Repro steps for 19w07a:

1. start a new world, creative mode

2. place down a bed

3. /time set night

4. sleep in the bed (works)

5. make a nether portal, and use it

6. return to the overworld through portal

7. /time set night

8. sleep in the bed (works)

9. move out of the spawn chunks, et /tp 1000 ~60 1000

10. place down a bed

11. /time set night

12. sleep in the bed (works)

13. make a nether portal, and use it

14. return to the overworld

15. /time set night

16. sleep in the bed (you should now be stuck in the bed interface)

The desync after visiting the nether, or visiting the end for a second time is still there in 19w04a

Using a portal to go to the Nether now triggers a desync in 19w03c. Also, going to the End a second time (ie after killing the dragon and leaving) also does it.

These seems similar MC-142114, but that's been closed.

I think I can repro this every time on 19w02a. 

1. Make a new world, in creative mode with cheats on.

2. Enter said world.

3. /tp to somewhere 1500 blocks from spawn (or fly if you want)

4. put down a bed

5. summon a cat owned by yourself (this is probably optional, but help illustrate things)

6. hopefully the cat will sit on the bed... remember where it is anyway

7. exit and save the game

8. re-enter

9. the cat will not be visible, but can be heard

10. /time set night

11. sleep in the bed

12. for me, on two different machines, and four different worlds, I now "drop" out of the bed when night is over, but cannot exit the bed interface

13. you can /kick yourself to shut down the world
