The Bug

When a fox teleports using a chorus fruit, the sound will play if the Players or the Friendly Creatures sound category is on.

To Reproduce

1. Turn off all sound categories except for Players.
2. Spawn a fox and make it eat chorus fruit, or use the command /summon fox ~ ~ ~ {HandItems:[ {Count:1b,id:"chorus_fruit"}

   ]}

3.  Wait until the fox teleports, and observe the fox making the sound
4. Repeat, but with the Friendly Creatures sound category being the only one turned on.

Solution

ChorusFruitItem calls both level.playSound and livingEntity.playSound. level.playSound calls it exclusively using SoundSource.PLAYERS. Remove this line, or do something else with it.
