[Duplicate] It is possible to obtain the suspicious sand and suspicious gravel items

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
