This bug allows netherite ingots, which are supposed to be fireproof, to burn.
Steps to Reproduce:
- Place some netherite ingots into a bundle.
- Throw the bundle onto the ground.
- Light it on fire with flint and steel.
The bundle, along with all the netherite ingots inside it, is burned.
Instead of the bundle burning with all of the items inside of it, it should drop the fireproof items, such as netherite ingots, leaving them unburned.
