The bug

In 1.18.2, falling blocks no longer produces block updated in the entity phase. The expected behavior would be for falling blocks to produce a block update when the sand entity gets ticked in the entity phase due to the sand block being removed.

How to reproduce

1. Build the attached build in a version prior to 1.18.2. Observe that the bottom block is pulled to the side before the second top piston pushes.
2. Build the same build in 1.18.2. The second iron block is no longer pulled to the side due to the lack of a block update in the entity phase scheduling an early block event.
