Warped roots hitboxes is not centered and not the same as in Java

This bug report is a parity issue with Java.

Summary:
In the Java version, the warped roots have a hitbox that is always centered. And also in the Java version the hitbox a bit more.
Java: 13 pixels high and 12 pixels on the sides (2 pixels off the edge).
Bedrock: ~8,5 pixels high and ~6 pixels on the sides.

Steps to reproduce:

1. Place warped roots.
2. Take a look at the dimensions of the hitbox.

Observed results:
The hitbox is not always in the center, and also has dimensions that do not correspond to the Java version.

Expected results:
The hitbox of the blocks must be the same.

Notes:
In the bedrock version, for some reason, the selection at the base is also not visible.
