Indestructible, Invisible fire

when you break the block underneath a fire in Minecraft bedrock edition the fire stays until you place a block underneath it and destroy the fire itself

 

The light from the fire is there you can take damage from it, and items can get deleted because of it.

Though the fire becomes invisible and doesn't seem to have a hitbox until you replace the block.

Steps:

1. use a flint & steel to set a block on fire
2. break the block underneath said fire
