Sheep eating grass does not trigger calibrated sculk sensors as expected

A callibrated sculk sensor powered with a power of 12 will detect blocks breaking as expected. However a sheep eating grass will not be detected despite it being detected as a block breaking when the calibrated sculk sensor isn't powered. Have tested with various sources of power 12 but the calibrated sculk sensor seems inable to detect the block breaking caused by a sheep eating grass whilst powered.
