title: webdriverio textarea set Text
body: <p>HTML:</p>
  
  <pre><code>&lt;form&gt;
    &lt;p&gt;
      &lt;label for="import-textarea"&gt;Use the "Export board" menu item in a board's menu, then copy the json from the resulting file.&lt;/label&gt;
    &lt;/p&gt;
    &lt;textarea class="js-import-json" placeholder="Paste your valid JSON data here" autofocus=""/&gt;
    &lt;input class="primary wide" type="submit" value="Import"&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>I want to set the text inside the textarea, with webdriver.io and tried different selectors:</p>
  
  <pre><code>const ta = browser.$('textarea');
  ta.setValue('Updated Text');
  
  const val = imp.selectByAttribute('placeholder', 'Paste your valid JSON data here');
  const text = browser.getText('.js-import-json=Paste your valid JSON data here');
  </code></pre>
  
  <p>But none of them seemed to work. Either i get no text at all or the selector could not be found on page.</p>
  
  <p>Any ideas?</p>
