The Bug
With the fix to MC-207329 sculk sensors are now able to detect when mobs are being fed. Though when taming/befriend and mob near a sculk sensor it doesn't activate
Reproduce
Get a sculk sensor
summon a NoAI wolf, dolphin, cat, ocelot, parrot near it
Feed the mob the appropriate taming/trusting food
❌ Notice the sculk sensor doesn't activate
Can confirm.
