domenic has just created a new issue for 
https://github.com/whatwg/dom:

== Attribute lowercasing does not appear to match browsers or 
web-platform-tests ==
I implemented the current attribute spec in jsdom pretty exactly. 
However, it failed the following web-platform-test 
([source](https://github.com/w3c/web-platform-tests/blob/56537bab9207d0c910c49305d4b55d5d5c639dea/dom/nodes/attributes.html#L41)):

```js
test(function() {
  var el = document.createElement("div")
  el.setAttribute("ALIGN", "left")
  assert_equals(el.getAttributeNS("", "ALIGN"), null)
  assert_equals(el.getAttributeNS("", "align"), "left")
  assert_equals(el.getAttribute("align"), "left")
}, "setAttribute should lowercase its name argument (upper case 
attribute)")
```

In my implementation `null` is returned for all three calls, because 
per spec `setAttribute` doesn't actually do any lowercasing.

If this is intentional we can just update web-platform-tests. I was 
unclear.
