Armor only drops by a player and not all stuff in inventory when killed by an irom golem.

When I was mining, I accidentally hit an iron golem and when the iron golem killed me with keepinventory off and I have blocks in my inventory, I normally die but thats not my reported bug I mean. Then if I go back where I die, my armor only drops and my stuff werent there. Hope Mojang fix this in 1.18 Betas. This bug is affected on 1.17.30.24. Well in affected version I put was 1.17.30.25 because it says no matches when typing 1.17.30.24 thats why.
