[MC-249409] Furnaces, blast furnaces and smokers don't cook without fuel in the bottom slot, even if they are already fired up

I was playing on my hardcore world that I just updated into the new snapshot and I noticed that the furnace wouldn't cook items and I was confused until I put a piece of coal into the bottom of the furnace and then I realized that the only way for the furnace to cook was to have an extra piece of coal in the furnace at all times. I wasn't able to test this with different items but I did include a video to show what is going on.

the problem is the same with a bucket of lava. no cooking until you put anything that will burn. even a stick will make the lava burn ok.

Super odd thing with lava buckets is that the game now recognizes empty buckets as fuel. Putting an empty bucket in a charged furnace fuel slot allows the smelting to continue.
