Vines on Dark Oak Trees spawn all the way up the tree

What Happened:
Vines that spawn with Dark Oak Trees go all the way up the tree, causing the leaves to be completely disconnected to the tree.

How to Replicate:
1. Either grow or find a Dark Oak Tree with Vines.
2. Observe the vines going all the way up the tree.

What’s Intended:
Much like Oak and other trees with vines. I expected the vines to begin where the leaves end. Allowing all leaves to be connected to the tree.
