What happens if you delete an attribute?  For the following test case, Chrome
outputs "string undefined", while Firefox and Opera give "string string":
data:text/html,<!doctype html><script>var el = document.createElement("a");
var type = typeof el.id; delete el.id; alert(type + " " + typeof
el.id);</script>

With manual newlines/spaces so it works reliably:

data:text/html,<!doctype html>
 <script>
 var el = document.createElement("a");
 var type = typeof el.id;
 delete el.id;
 alert(type + " " + typeof el.id);
 </script>

I'm told this is a WebIDL issue.
