Incompatibility (Bug)

What behaviour is expected:

Player should arrive at bed after leaving exit portal.

What behaviour is observed:

Player arrives at world spawn.

Steps/models to reproduce:

Start a server.
Set time to night.
Place bed (not obstructed)
Sleep in bed.
Create end portal.
Go into end.
Run save-all.
Stop Server.
Start Server.
Player is still in end.
Have player go through an exit portal.
Player will end up at world spawn, not their bed. Further attempts to go through an end exit portal will yield same results.

Did a cross check of some NBT files for my player data.
I will attach 3.
File 1 (plain UUID) is bed home set (spawn world selected as "world")
File 2 (UUID (1))is after a restart while still in the end (spawn world also selected as "world")
File 3 (UUID (2))
Paper_issue_157_playerdat_files.zip
is after leaving the exit portal (Spawn coordinates remain the same, but spawn world is counted as "world_the_end")
Because this is changed, my player's bed is not seen because it's looking for a bed in that world.
