Template function returns html, the html is then stripped of it's class

[Steveiwonder]

While testing this library I found an issue which seems odd.
I tested this as my template function

template: function(item, element, data){
  let html =  `<h6><i class="${item.icon}"></i>${item.content}</h6>`;
  console.log(html);
  return html;
}
}

The class from the i element is removed once it's returned, i can see in the console the html output is correct

but this is the elements in the dom

EDIT:

After some debugging it looks like a call to util.xss(content) strips the class

Thanks
