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.
