title: Ionic <ion-item> between <ion-label> and <ion-datetime> not showing up
body: <p>I am trying to make content appear between a stacked ion-label and ion-datetime input, but it just doesn't show up. What am I doing wrong? This is the html code:</p>
  
  <pre><code>&lt;ion-item&gt;
    &lt;ion-label stacked &gt;
      &lt;p&gt;Test label&lt;/p&gt;
    &lt;/ion-label&gt;
    &lt;ion-item&gt;
      &lt;img src="https://www.shorturl.at/img/shorturl-square.png" /&gt;
      &lt;p class="multiline-text"&gt; Test text &lt;/p&gt;
    &lt;/ion-item&gt;
    &lt;ion-datetime displayFormat="MMM D, YYYY" placeholder="MMM D, YYYY"&gt;&lt;/ion-datetime&gt;
    &lt;button large class="transparent-button" style="align-self: flex-start; margin-top:12px;" ion-button item-right (click)="toggleHelp(input)"&gt;
      &lt;ion-icon style="font-size: 1.7em; align-self: flex-start;" name="ios-help-circle-outline"&gt;&lt;/ion-icon&gt;
    &lt;/button&gt;
  &lt;/ion-item&gt;
  </code></pre>
