<p>This tests for a bug in GMail's Editor, they try to extract the contents of a range that has had it's contents removed from the document by an editing command.  You should see 'dogfood' unstyled below.</p>
<div id="div" contenteditable="true">dog<a href="http://www.google.com/">food</a></div>

<script>
var div = document.getElementById("div");
var text = div.firstChild;
var link = div.lastChild;
div.focus();

var r = document.createRange();
r.setStart(text, 0);
r.setEnd(link, link.childNodes.length);

document.execCommand("SelectAll");
document.execCommand("RemoveFormat");

r.extractContents();
</script>
