The bug
Sculk sensors are not activated upon camels dashing. This is unexpected, as the camel is physically moving.
To reproduce
Place a sculk sensor.
Summon a camel and saddle it.
Mount the camel.
Wait for the sculk sensor to stop.
Dash.
Expected result
The sculk sensor would pick up the vibration.
Observed result
The sculk sensor is not activated, and only activates when the camel touches the ground.
I can confirm this behavior.
