The bug

The planes composing dripleaf plants do not mirror on the back as one would expect, resulting in physical/illogical weirdness.

How to reproduce

1. Place a small dripleaf
2. View a specific leaf of the block from above
3. View the exact same section of that leaf from below
4. Note that the exact texture pattern at that position is different, even though it should be the same
