Sneaking once a big dripleaf has begun to tilt does not stop it from tilting

Once a dripleaf begins to tilt, sneaking does not stop it from tilting all the way. However, when jumping or moving off of the dripleaf in this situation, it will stop tilting and return to the upright position.

Since sneaking stops it from tilting normally, it should also stop it from tilting after it begins just like jumping does.
