I create iframe in some DIV using JS document.createElement("IFRAME") and write there some content using el.contentWindow.document.open() etc.
After that if I use insertBefore and move this div with iframe to another place in DOM I'll loose everything in frame (I see empty HEAD and BODY in iframe).

Reproducible: Always

Steps to Reproduce:
1.Create iframe using JS
2.Write some content to iframe
3.Move iframe to another place in the DOM
4.Check that you lost all iframe content
Actual Results:  
You see empty iframe without any content.

Expected Results:  
You see content that you created in the iframe.

<html>
<head>
<script>
function swit() {
	var d = document.getElementById("par");
	var d1 = d.getElementsByTagName("DIV")[0];
	var d2 = d.getElementsByTagName("DIV")[1];
	
	d.insertBefore(d2,d1);
}

function setc() {
	var d = document.getElementById("par");
	
	var el = document.createElement("STRONG");
	el.innerHTML = "111111";
	el.style.color = "green";
	d.getElementsByTagName("DIV")[0].appendChild(el);
	var el = document.createElement("IFRAME");
	d.getElementsByTagName("DIV")[0].appendChild(el);
	with (el.contentWindow.document) {
		open();
		write("1111111111111111");
		close();
	}
	
	var el = document.createElement("STRONG");
	el.innerHTML = "222222";
	el.style.color = "red";
	d.getElementsByTagName("DIV")[1].appendChild(el);
	var el = document.createElement("IFRAME");
	d.getElementsByTagName("DIV")[1].appendChild(el);
	with (el.contentWindow.document) {
		open();
		write("22222222222222222");
		close();
	}
}
</script>
</head>
<body onload="setc();">

<div id="par">
	<div id="1"></div>
	<div id="2"></div>
</div>

<input type="button" onclick="swit();" value="SW" />

</body>
</html>
Calling insertBefore reloads the iframe but content created with script can't be reloaded...
