<style>
blockquote {
    color: blue;
    border-left: 2px solid blue;
    margin: 0px;
    padding: 0 0 0 20px;
}
</style>

<p>This tests pasting a nested blockquote into a blockquote. The first line below should be singly-blockquoted, and the second should be doubly-quoted.</p>
<div contenteditable="true"><blockquote type='cite' id="block">One</blockquote></div>

<script>
var sel = window.getSelection();
var block = document.getElementById("block");

sel.setPosition(block, 3);
document.execCommand("InsertHTML", false, "<span><blockquote type='cite'><blockquote type='cite'><div>Two</div><div>Three</div></blockquote></blockquote></span>");
</script>
