Smelting ores in blast furnace and food in smoker does not generate xp

After exploring the deep caves I got lots of ore including copper ore, iron ore and gold ore. But burning them in blast furnace did not afford me experience. I was disturbed after burning those ore but get no xp. It occured to me that when testing this issue in creative mode I can confirm this bug did exist.

Ways to reproduce :

1.Place a blast furnace.

2.Put some ore and burn, take 64 ore for example.

What happens:

You get 64 ingots but no xp

What should happens:

You get 64 ingots with lots of xp

Testing with foods and smoker result in the same problem, those two working blocks don't work well.
