The Bug:
Sculk sensors are not activated upon collecting Dragon's Breath.
Steps to Reproduce:
Collect the dragon's breath whilst a sculk sensor is nearby.
→ ❌ Notice how the sculk sensor does not activate upon doing this.
Additional Information:
Quote from the 20w49a Changelog, "A vibration is anything that causes physical motion". I would definitely consider this as physical motion, as you are physically performing this task.
Closely relates to MC-207677.
