This bug report is a parity issue with Java.

Summary:
Big dripleaf's stem texture doesn't match java.
This is especially evident along the sharp edges in the Java version. There are no sharp edges in the thigh. And if you take a closer look, the differences will become clear not only in the edges)

Steps to reproduce:

1. Place big dripleaf at least two blocks high (for a better view of the texture).
2. Take a look at the stem texture of the big dripleaf.

Observed results:
The textures are different. Especially visible on the smooth edges in the thigh version.

Expected results:
The texture will be the same in both versions.

Notes:
Also, there is a bug in the texture of the stem like hanging roots MCPE-122362.
