Oh, and the testcase is basically this:
<iframe></iframe>
<script>
var i = document.querySelector("iframe");
var c = i.contentWindow.getComputedStyle(i.contentDocument.body);
i.style.display = "none";
try {
alert(c.getPropertyValue("direction"));
} catch(e) {
alert("Exception thrown: " + e);
}
</script>
