title: Vuejs Select Dropdown writing an option thats not present makes selected value null
body: <p>I am trying to use the VueJs Select component (<a href="https://vue-select.org" rel="nofollow noreferrer">https://vue-select.org</a>) but what I want to achieve is having the user to write an option on the input field that is not on the presented defaulted options.</p>
  
  <p>When I write into the text field it shows no results, and the handler of selected option tells me that the value is null, why is that?</p>
  
  <p>Here is my v-select:</p>
  
  <pre><code>&lt;v-select :options="sortingOptions" v-model="sortingDefinition" taggable @input="setSelected" :multiple="false"&gt;&lt;/v-select&gt; 
  </code></pre>
  
  <p>I passed taggable as property because it tells on the documentation the following:</p>
  
  <p><em>To allow input that's not present within the options, set the taggable prop to true.</em> (<a href="https://vue-select.org/guide/values.html#tagging" rel="nofollow noreferrer">https://vue-select.org/guide/values.html#tagging</a>)</p>
  
  <p>Then when I start typing something and end, then stop the focus on the input (dropdown) field, the following function is not triggered with the new value that I typed why?</p>
  
  <pre><code>setSelected(value){
          console.log('value: ', value);
  },
  </code></pre>
  
  <p>Any thoughts?
  Thanks</p>
