This bug report is a parity issue with Java.
In the Java version of the small dripleaf it is not a complete block, but in the bedrock version it is a complete block.
In the Java version, the hitbox lacks two pixels at the edges and three pixels in height.
Steps to reproduce:
- Place small dripleaf.
- Take a look at the small dripleaf hitbox.
The hitbox is a complete block.
The hitbox will be the same as in Java.
