When you're placing redstone dust near a warden/sculk sensor, it doesn't get picked up as a vibration. This means that the sculk sensor/warden won't detect player placing the redstone dust.

How to Reproduce

1. Place a sculk sensor
2. Place redstone dust
3. Check and see if the sculk sensor detects it
   ---> Sculk sensor ignores/doesn't detect player placing redstone dust.
