Potato glitch

What I expected to happen was the potato to grow normally after being planted without a water block(which is how wheat, pumpkin stems, and melon stems act.)

What actually happened was potato uprooted after a few seconds. It acted just like a tilled dirt block with no water near enough to it for it to get hydrated

Steps to Reproduce:
1. till dirt, making sure it isn't with-in 4 blocks of a water block(flowing or not)
2. plant potato on the tilled soil
3. after a random time, the crop should uproot
