== [cssom] getComputedStyle can return null? ==
Related to
https://github.com/w3c/csswg-drafts/issues/571
and maybe
https://github.com/w3c/csswg-drafts/issues/219

In Gecko, the following alerts null

```
<!DOCTYPE html>
<iframe style=display:none 
srcdoc="<style>body{background:blue}</style>x"></iframe>
<script>
onload = () => {
alert(window[0].getComputedStyle(window[0].document.body))
}
</script>
```

In WebKit/Chromium/Edge 13 it alerts [object CSSStyleDeclaration].
