title: How to globally add aria-hidden to buttons in all ionic alert controllers?
body: <p>Is it possible to add <code>aria-hidden</code> to buttons in all ionic alerts in my app?</p>
  <p>For example, my code is below:</p>
  <pre><code>private createAlert(): void {
     this.alertCtrl.create({
        buttons: [{ text: 'Ok' }],
        header: 'Alert',
        message: 'Test Alert',
     })
     .then((alert) =&gt; {
        alert.present();
     });
  }
  </code></pre>
  <p>I want to be able to add <code>aria-hidden</code> to the OK button so that it's not read out by a screen-reader. I can probably do this using query selector and adding it to the element via javascript, but I need it done on a global scale to affect all my alerts. How can I do this?</p>
