title: Vuetifyjs form validation with mask
body: <p>I create one v-form in my component, inside this v-form I put a v-text-field with a mask and a rule to not null</p>
  
  <pre><code>&lt;v-text-field mask="###.###" :rule="[v =&gt; !!v || 'Required']"&gt; ... &lt;/v-text-field&gt;
  </code></pre>
  
  <p>but if my user type 22, when I try to validate the form I fot valid (because the text are not null, in my rules) but he don't match with my mask.. how can I get both validations? tks</p>
