Wind charge cancels fall damage even after landing

If you make a really tall pillar, and use a wind charge to jump on top of the pillar, then walk off the pillar, you will not take any fall damage at all.

What I expected to happen was...:
After I land on the pillar using a wind charge, if I fall, I take fall damage.

What actually happened was...:
I did not take any fall damage.

Steps to Reproduce:
1. Make a pillar 11 blocks tall and add three snow layers on top
2. Use a wind charge to jump on top of the pillar(hold shift while looking down, then release shift and also do right click + hold jump)
3. After you land on the pillar, walk off of the pillar(it may be a bit inconsistent)
