Is your feature request related to a problem? Please describe.
When you transform a tree using a command or transformation potion the roots don't change to the type that you have changed the tree to.

Describe the solution you'd like
I would like that roots would change to the tree type you have selected to change to.

Additional context
Here you can see that a redwood tree has been changed to spruce, but the roots have not changed to spruce, but have stayed redwood.
