 I believe that adding both `tabindex="-1"` and `aria-hidden="true"`
 attribute on the RSS icon's wrapping `a` tag (not on the `img` itself) is
 an elegant and standards-based solution to remove the linked icon from the
 Accessibility DOM. This would solve the issue of duplicate link text
 leading to different URIs violating the WCAG 2.4.4 standard.
