Steps to reproduce


headers IDL attribute is a string but should be DOMTokenList. (This also applies to some other things that may not be currently supported in Edge like a/, link.relList etc.)


Simple test:

<!DOCTYPE html>
<table><tr><td id=td headers="z"></table>
alert(td.headers instanceof DOMTokenList);
