Lost all my stuff in choco because it wasn't my fault

Hello. In choco today, I was flying with elytra and fireworks, and I died because of the lag. It dropped me into the void, and I perished. I only have one screenshot which sadly doesn't show my elytra, but I does show that I did have full diamond.

The enchantments I had on my gear:

Diamond Helmet - Protection 3, Unbreaking 3

Diamond Chestplate - Protection 3, Unbreaking 3

Diamond Leggings - Protection 3

Diamond Boots - Unbreaking 3

I have a diamond sword with sharpness 4 and unbreaking...
