Crafting bamboo into scaffolding gives you 8 times the furnace fuel for free

The issue

Six bamboo creates six scaffolding. So it makes sense that bamboo and scaffolding has the same fuel time (as it was previously). Now, scaffolding burns for 8 times as long as bamboo, meaning you get something from nothing.

It's possible this was ported from bedrock? Though bedrock has always been wrong with this: MCPE-42949

Possibly this is invalid considering the change was obviously made intentionally, but it seems like a sanity regression. All other items have fuel time preserved across crafting.
