Add Font Awesome to breadcrumbs

I’d like to replace the “Home” link in the breadcrumbs to an icon. My theme is using a variant of the Font Awesome icon’s. I need to add <i class="x-icon x-icon-home" data-x-icon="" aria-hidden="true"></i>

When I add that code, the data-x-icon and aria-hidden attributes are stripped, and I’m left with <i class="x-icon x-icon-home"></i>

Even using Font Awesome’s version of the icon, the aria-hidden attribute is still stripped from the HTML.

Is there anything I can do to correct this?
