[MC-277860] Sand starts falling when placed on 2 or more snow layers

How to reproduce:
1. Place between 2 and 8 snow layers
2. Place a block of sand on top.

Observed behaviour:
Sand starts to fall after beeing placed on the snow layers

Expected behaviour:
Multiple snow layers should be able to support a block of sand, since sand cannot replace them when falling.

Does MC-143822 describe your issue?

WAI: MC-139493.

@Viradex Not really, because it starts falling even if it is visually touching the top of the snow layers

@Dhranios No, the way I understand it, that bug is related to the sand staying in entity form, which was a bug.

My issue is, that the sand in block form starts to fall, even when it is visually touching the top of 8 snow layers.
That behaviour is normally only present for blocks it can actually replace when landing in them. >1 Snow layer cannot be replaced that way.

Quoting the mod comment on MC-139493:

Seems to be fixed in 19w06a alongside MC-90523. The falling block now replaces the snow layers.

The latter part has broken since, which is MC-143822. That they fall is WAI.
