Step by step scenario

instructed in the link

Actual Solution

change v-show to v-if for nested draggable could avoid other nodes get updated that triggered by the target node, but it will force the target node to be re-rendered every time when v-if is toggled.

Expected Solution

Keep v-show on nested draggable and Only trigger update for the changed node.
