Steps to reproduce

2. Add anchor and button in the banner actions

<igx-banner #cookiesBanner>
  <igx-icon>settings</igx-icon>
  <span i18n>This site uses cookies.</span>
  <igx-banner-actions>
    <a href="https://www.cookiesandyou.com/" target="_blank" rel="noopener" i18n>Cookies and You</a>
    <button igxButton igxRipple (click)="acceptCookies()" i18n>I Understand</button>
  </igx-banner-actions>
</igx-banner>
