title: Vuetify text-area empty OR less than 200 character rule
body: <p>Im using Vuetify and trying to get a text-area to validate ONLY if there are more than 200 characters.</p>
  
  <p>I want to ONLY make the field validate if the user has 1 or more characters, but be less than 200 characters IF it is at least 1 character. This filed is not required BUT if they choose to type data into it i want to make sure its is 200 characters or less.</p>
  
  <pre><code>&lt;v-textarea
      v-model="description"
      :counter="200"
      :rules="[v =&gt; (v &amp;&amp; v.length &lt;= 200) || 'Description must be 200 characters or less']"
      label="Description"
      height="125"
      no-resize
      outline
  /&gt;
  </code></pre>
