Suspicious Sand or don't have any loot or don't generated with loot.

Respected Mojang Team,
Hi! I reported a bug few months or weeks ago! And now I am updating this bug report as this is important to resolve this bug before 1.20 releases.
Steps to reproduce:
. Create a world with experimental toggles Next Major Update, Sniffer or even 1.5 sneaking on then put any seed or select seed from seed template after that create a world.
. If you are in creative, then change your world in survival mode. I prefer to create your world in survival mode.
. After the world is created go to archeology sites or tails ruins, then find a suspicious sand or gravel.
. Apply brush on it. To find a loot.
Observations:
. When you apply a brush on suspicious sand or gravel, attentively observe that when suspicious sand or gravel started to break slowly by slowly you don't see any loot coming out from it by slowly by slowly.
. The above observations tell that suspicious sand or gravel should be generated with loot. So that, whenever you apply brush on it in survival mode or world then it should give you a loot instead giving you nothing.
. All the above two observations saying that Suspicious sand or gravel should be generated with loots.
Important Information:
. Seed: -1834063422
. Desert Temple Location/My Position: -246, 61, 202
Or
. Location: -248 64 200
. Affected Version: 1.19.81
. Minecraft World created in the affected version: 1.19.81
. The Minecraft world should be created in survival mode only. I prefer that you should create the world by yourself to check the bug.
. The bug is on the latest stable version 1.19.81

I hope you will look forward to this issue.
Thanks!
