How should one use appendChild or similiar methods
of arsd.dom library?
You need to remove the element from the first document before
trying to append it to another.
Try something like:
content.appendChild(firstElements[0].removeFromTree());
removeFromTree is a convenience method to do
parentNode.removeChild(this).
Since an element can only exist in one place in a tree at a time,
it will give the assert error if you try to add it to two places
at once.
