Concrete powder falling block entities disregard the water level of flowing water.

When falling concrete powder is positioned above flowing water without visibly touching it, it transforms into concrete. They disregard the water's height, as outlined in MC-150455 or MCPE-46074. In the provided video, if the water beneath the concrete powder were a source block, the process would function correctly, but this is not the case. As a result, the concrete powder transforms into concrete prematurely.
