I'm using Vuetify to render a combobox, when the user change the value of that combobox I want to display a message asking to confirm the operation, but I'm not able to prevent the change of the value if the user disagree to change the value. I tried with both `input` and `change` events.

Below the HTML:

```
  <v-app>
    <v-container class="indigo lighten-5">
      <v-row no-gutters>
        <v-col cols="12">
          <v-select v-model="o.selected" :items="values" @input="inputSelect"></v-select>
        </v-col>
      </v-row>
    </v-container>
  </v-app>

```

while the methods that listens for changes is:

```
    inputSelect(val) {
      console.log(val);
      if (confirm(`Do you really want to change the value to ${val}?`)) {
        console.log("ok");
        return true;
      } else {
        console.log("ko");
        return false;
      }
    }

```

I created a [pen](https://codepen.io/alessmar/pen/xxONOdZ) to reproduce the behavior.
