[whatwg] Case canonicalization for reflected enumerated attributes limited to known values

Actually, it goes further than that.  Everyone but IE seems to just
return the value of the content attribute when you do a get on the IDL
attribute:

<!doctype html>
<script>
  var el = document.createElement("form");
  el.setAttribute("method", "invalid value");
  alert(el.method);
</script>

IE alerts "get", everyone else alerts "invalid value".  Are non-IE
implementers interested in changing to match IE here?  IE's behavior
seems more useful.
