Standing on a sculk sensor, even without moving, makes the sensor activate. This triggers sculk shriekers, but does not alert nearby wardens in any way in my experience.

To reproduce:

1: Place a sculk sensor and a warden nearby each other

2: Enter survival mode

3: Stand still on the sensor, not making sound, but still activating the sensor

Expected result: The warden should notice the sensor activating, as it does in java edition

Actual result; The warden doesn't notice the sensor activation
