Using /item replace command can trigger Sculk Sensor unexpectedly

Putting armor on manually or with a command triggers the Sculk Sensor.

However, running a command like 

/item replace entity @p armor.chest from entity @p armor.head

without wearing any armor

or 

/item replace entity @p armor.chest with air

 still triggers the Sensor, despite the output being that the slot was replaced with air and not armor. No sound plays for the air "equipping" event.
