This issue was originally filed by alexe.kaigorodov@gmail.com

following code:

const String htmlEL = r''' <dialog id="d1"> <p>foobar</p> <button>OK</button> </dialog> ''';

void main() { document.body.appendHtml(htmlEL); var d1 = document.getElementById('d1'); print("d1 is ${d1.runtimeType}"); }

prints

d1 is UnknownElement

In 1.8 it returns HtmlElement rather than UnknownElement but it still seems incorrect.
