When killing a sheep with an unenchanted stone sword, they drop cooked mutton instead of raw mutton stone sword

Today I just updated from 1.13 (not 1.13.1 or 1.13.2) to the latest snapshot. I went out to go kill some sheep for food in a plains biome with a stone sword that I crafted before updating. The sword didn't have any enchantments on it. I know this is a minor bug, but I thought I'd report it anyway.
