When you till the ground with a shovel and then put powdered snow on it you walk normally and you can put one block of powder on the ground and land on it without dying from any height

What I expected to happen was...:
i thought that it would take more powdered snow so you can survive the fall. and I thought that you should slow down when the powdered snow is on the tilled ground (tilled by a shovel right-click a grass block

What actually happened was...:
i didn't slow down when the powdered snow was on the tilled ground. and I can survive any height when I land on one block of powdered snow

Steps to Reproduce:
1. till a grass block with a shovel
2. . put powdered snow on tilled ground
3. walk on powder snow

Steps for surviving any height with one block of powdered snow
1 place powder snow
2 go to any high height ( I went to max height)
3 fall on powder snow
4 you survive a high height
