I was in the Overworld using fire for some random reason, when suddenly, I place water on the block it was taking up and it made a sound as if a block of wood had just been broken.
I tested this with a water bucket ONLY. I'm not sure if it works with a water source block or lava.
Steps to Reproduce
1. Light a fire and make sure it doesn't go out.
2. Get a bucket of water from your inventory (survival or creative, possibly adventure)
3. Place the water on the block that the fire is taking up and you should hear the noise of a block of wood being smashed.
