Falling blocks don't play their breaking sound when their DropItem tag is set to 0

Run

/summon minecraft:falling_block ~ ~ ~ {BlockState:{Name:"minecraft:pointed_dripstone",Properties:{vertical_direction:"down"}},FallHurtMax:40,Time:15,DropItem:1}

and notice how the breaking sound plays when the dripstone lands.

Now run

/summon minecraft:falling_block ~ ~ ~ {BlockState:{Name:"minecraft:pointed_dripstone",Properties:{vertical_direction:"down"}},FallHurtMax:40,Time:15,DropItem:0}

and notice how the breaking sound does not play this time, while the only difference is that it doesn't drop its item.

This doesn't make sense, as the dripstone is still breaking and should still play the sound, even if its not dropping the item. This also applies to anvils breaking.
