Smooth animation in vue.js #2?

Question

Vue.js

Help, please once again deal with one more subtlety of animation.
I need to achieve a scrolling effect like here .
But to do it with vue-router connection.
By analogy, I run into the fact that it is impossible to wrap the router-view in a transition-group, an error pops out that each block must have a :key property.
Here is a non-working example , please help me to achieve the effect with a router like here .
