When you break the big dripleaf in the tilted state from the stem, the big dripleaf on the top doesn't drop, instead, it floats for a moment before it breaks itself.

Step to Reproduce
1. Place down big dripleaf and bone meal them to make it taller.
2. Stand on the big dripleaf until it is fully tilted.
3. Break the bottom of the dripleaf.
---> The top part of the big dripleaf where it is still tilted, still floats in the air.
