title: HTML tags are not working in Ionic 5 Alert text
body: <p>I have migrated the following code from Ionic 3 to Ionic 5</p>
  
  <pre><code>   const alert = await this.alertCtrl.create({
        subHeader: "About" + " &lt;b&gt;" + this.user.name + "&lt;/b&gt;",
        message: "Test Messgae",
        buttons: [
          {
            text: 'Close',
            role: 'cancel',
            handler: () =&gt; {
            }
          }
        ]
      });
      await alert.present();
  </code></pre>
  
  <p>In Ionic 3 the user name is displayed in Bold font but in Ionic 5 the HTML tags are not working and &lt; b > tags are displayed as text. 
  Please suggest how can I style text in alert in IONIC 5.</p>
