How to add drag-drop event handlers at v-app level?

[Tennyleaz]

Hi,
I would like my whole webpage (v-app) to handle file drag and drop. I tried to add something like:

<template>
  <v-app v-on:dragover="dragover_handler" v-on:drop="drop_handler">
    <v-app-bar app dense>
      ...
    </v-app-bar>
    <v-main>
      <Nuxt />
    </v-main>
  </v-app>
</template>

It seems that v-on:dragover and v-on:drop have no effect. Where else could I add these handlers?
