Bug Description:
In 1.21.8 and earlier, it was possible to redirect a fueled furnace minecart by right-clicking it while holding any item (this was intended per MC-122011). As of 1.21.10 this only works if you fuel it using coal or charcoal.
Steps to Reproduce:
Build a rectangular track of decent size (using only regular rails)
Place a furnace minecart on the track
Power it with coal or charcoal
✅ It begins moving down the trackWhile standing next to the track, interact with the furnace minecart while holding coal or charcoal while it is coming at you
✅ The furnace minecart is begins moving in the other directionRepeat step 4 but do not hold coal or charcoal
❌ The hand animation plays, but the minecart does not switch direction
Expected Result:
The furnace minecart would switch direction
The bug is actually that interacting with a furnace minecart while not holding coal or charcoal no longer redirects it. I will rewrite the report accordingly
