To reproduce

1. Run this command:

   /setblock ~ ~ ~ minecraft:suspicious_sand{item:{id:"minecraft:nether_star",Count:1b}}

2. Place TNT near the suspicious sand and interact with it with a flint and steel

Observed result

The nether star inside of the suspicious sand is explosion-proof and drops .

Actual result

The nether star does not drop.
