title: How to set a span value with capybara?
body: <p>Does anyone know how to set a value to span tag using capybara?</p>
  
  <p>I tried using <code>element.set</code> or <code>element.send_keys</code>, they only selected the targeted element without modifing the previous value.</p>
  
  <pre><code>&lt;div data-offset-key="bbpvo-0-0" class="_1mf _1mj"&gt;&lt;span data-offset-key="bbpvo-0-0"&gt;&lt;span data-text="true"&gt;aa&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
  </code></pre>
  
  <p>HTML snippet is above, I want to set <strong>aa</strong> to <strong>bb</strong>.</p>
