My sidebar is laying over the router-view but it should be "blocking" the space.

In my App.vue there is following code
<template>
<v-app id="app">
<v-container>
<sidebar class="d-block"/>
<router-view class="d-block"></router-view>
</v-container>
</v-app>
</template>
Due to the d-block class of Vuetify I'd expect the sidebar to not overlay.
The sidebar is basically copied from the original API
<template>
<v-container>
<v-navigation-drawer
v-model="drawer"
:color="color"
:permanent="permanent"
:app="app"
dark
>
<v-list dense nav class="py-0">
<v-list-item-content>
<v-list-item-title>Application</v-list-item-title>
<v-list-item-subtitle>Subtext</v-list-item-subtitle>
</v-list-item-content>
<v-divider></v-divider>
<v-list-item v-for="item in items" :key="item.title" link>
<v-list-item-icon>
<v-icon>{{ item.icon }}</v-icon>
</v-list-item-icon>
<v-list-item-content>
<v-list-item-title>{{ item.title }}</v-list-item-title>
</v-list-item-content>
</v-list-item>
</v-list>
</v-navigation-drawer>
</v-container>
</template>
