title: Ionic 4 <button ion-item> not showing properly
body: <p>I'm aiming for a page where there's a searchbar along with a list of items that are clickable. I’ve been using the code that’s in ionic docs to make it happen but it's not giving me the right result.
  This is the code:</p>
  
  <pre><code>&lt;ion-header&gt;
    &lt;ion-toolbar&gt;
      &lt;ion-title&gt;Page&lt;/ion-title&gt;
    &lt;/ion-toolbar&gt;
  &lt;/ion-header&gt;
  &lt;ion-searchbar (ionInput)="getItems($event)"&gt;&lt;/ion-searchbar&gt;
  &lt;ion-content&gt;
    &lt;ion-list&gt;
      &lt;button ion-item *ngFor="let item of items" (click)="itemSelected(item)"&gt;
        {{ item }}
        &lt;/button&gt;  
      &lt;/ion-list&gt;
  &lt;/ion-content&gt;
  </code></pre>
  
  <p>Yet when I look at it on the app it shows the items like normal buttons, like this:

  <p>What am I doing wrong?</p>
  
  <p>Edit: I am aiming for it to look like shown here <a href="https://ionicframework.com/docs/components/#list-lines" rel="nofollow noreferrer">https://ionicframework.com/docs/components/#list-lines</a></p>
