Why does vue-router remove the component on transition?

Question

Vue.js

When moving from one component to another, vue removes the previous component. Is this normal or can I leave it somehow so that it does not render on a new one?

const router = new Router({
  routes: [
    {
      path: '/',
      name: 'MainPage',
      component: MainPage
    },
    {
      path: '/contacts',
      name: 'ContactsPage',
      component: ContactsPage
    }
  ]
})

<router-view></router-view>
