Before 1.19.80.20, mobs made the player eat sound (random.eat) when they were fed food. This was fixed in 1.19.80.20 (although there's no bug report I could find), but bees were not included in the fix. This is because the "eat" sound key in sounds.json was not defined to "".
Can confirm fixed in 1.20.0.22, please change the resolution to match.
