The bug
Sculk sensors are activated upon interacting with minecarts with hoppers; this shouldn't be the case based on this comment by @unknown: "Updated to reflect that it should only emit vibrations for entities that hold chests. Hoppers emitting a vibration to begin with is a bug."
To reproduce
Place a minecart with hopper.
Place down a sculk sensor.
Open the minecart with hopper.
Expected result
The sculk sensor would not activate.
Observed result
The sculk sensor activates.
