A spectator can occupy a bed if they enter it and then are switched to spectator mode

The bug

A spectator can occupy a bed if they enter it and then are switched to spectator mode. Expected behavior would be that the spectator would get kicked out of bed and that another player would have been able to join the bed.

How to reproduce

1. Place a bed and go into it. This requires the player not to be in spectator mode
2. /gamemode spectator
   → Notice you are still in a bed
3. Ask another player to go into the bed you are occupying
   → Notice they can't because the bed is occupied
