Gravity blocks - Falling Entities (eg Sand) Break and Drop as Items Unexpectedly

^{Update by [Minecraft] Mega_Spud (Jay Wells):}
Summary:
Falling blocks such as sand will break even when landing on blocks that have a full height hitbox, such as hoppers, upturned stairs, or top-half slabs.

Steps to Reproduce:

1. Place sand a few blocks above an upturned stair block

Observed Results:
The sand will break and drop as an item as it hits the stair block.

Expected Results:
I expected the sand to fall and land as a block, not drop as an item.

Screenshots/Videos attached: Yes

Notes:
List of blocks that cause the falling entity to break, that do not in Java:

• Fence posts
