Loot chests from various structures generate with different items on realms compared to a local copy of the same seed.

Steps to reproduce;

1. Create a new local world using the seed 3637093744542242594 (or any seed)
2. Upload the created world to a realm server
3. Open the local copy of the world and locate any structure that generates with loot chests, for example the pillager outpost at x: 760 z: 2,888
4. Open a chest in the structure and take note of the items inside
5. Open the realms version of the world and locate the same structure and loot chest
6. Compare the items in the realm loot chest to the same chest on the local world

 
Expected results - The loot will be the same
Actual results - The loot is different

This bug seems to happen with any structure that generates with loot chests, Including; Dungeons, Outposts, Mansions, Nether Fortress, etc.
