<p>This tests for a bug where newlines would not be preserved during copy/paste. Below you should see two paragaphs containing "Hello World!" and an empty third paragraph with the caret in it.</p>
<div id="root" contenteditable="true">Hello World!<div id="div"><br></div></div>

<script>
root = document.getElementById("root");
root.focus();
document.execCommand("SelectAll");
document.execCommand("Copy");

selection = window.getSelection();
div = document.getElementById("div");
selection.setPosition(div, 0);
document.execCommand("Paste");
</script>
