Sculk sensors are activated upon interacting with minecarts with hoppers

The bug

Sculk sensors are activated upon interacting with minecarts with hoppers; this shouldn't be the case based on this comment by [Mojang] Brandon Pearce: "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

1. Place a minecart with hopper.
2. Place down a sculk sensor.
3. Open the minecart with hopper.

Expected result

The sculk sensor would not activate.

Observed result

The sculk sensor activates.
