Steps to reproduce:
Create a bubble column with soul sand
Drop a suspicious sand on it
When the falling sand time expires it drops due to the NBT having DropItem set to true
Expected behavior:
Nothing drops as you can't obtain the sand when breaking it
A video reproducing it can be seen here: https://youtu.be/SQeW9f_tvtY
