I picked up a shulker box containing many enchanted tools, placed it into my ender chest, entered the nether, then had my game crash due to a complication with MC-200083. When I reloaded my game, my inventory and ender chest were in the state they were before I picked up the shulker box (not containing shulker box), and the world was in the state it was after (not containing shulker box).

To reproduce:

• Launch Minecraft and load a world.
• Break and pick up or place a block.
• Kill Minecraft with SIGKILL or by reproducing MC-200083 and otherwise causing the opened application to crash (which takes Minecraft with it). Using alt+F4 or holding F3+C to force a crash does not reproduce the bug.
• Launch Minecraft and load the world again.

Expected behavior:

• The game should revert to the last "safe" autosave. Losing 5 minutes of progress is better than save corruption.

Actual behavior:

• The player and world will be a mix of before and after you placed or picked up the block. Either the item is present in both the world and the inventory, or it is present in neither.
