title: TinyMCE inline option not working?
body: <p>I have a tinymce 4.7.4 field.</p>
  
  <p>I have applied <code>inline</code> option according to the documentation (<a href="https://www.tinymce.com/docs/configure/editor-appearance/" rel="noreferrer">https://www.tinymce.com/docs/configure/editor-appearance/</a>) and it returns a js error? So tinymce field breaks. </p>
  
  <pre><code>Could not initialize inline editor on invalid inline target element &lt;textarea id="Description" class="text ui-widget-content ui-corner-all input-sm tinymce" cols="20" name="Description" rows="2"&gt;
  </code></pre>
  
  <p>The snippet:</p>
  
  <pre><code>tinymce.init({
          selector: "textarea",
          inline: true,
          toolbar: "undo redo | bold italic | bullist numlist"
          });
  </code></pre>
