<p>This tests for a hang when indenting a fully selected table twice.  You should see a twice indented table, with four cells, below.</p>

<div id="div" contenteditable="true">
    <table border="1">
        <tr><td>One</td><td>Two</td></tr>
        <tr><td>Three</td><td>Four</td></tr>
    </table>
</div>

<script>
div = document.getElementById("div");
div.focus();
document.execCommand("SelectAll");
document.execCommand("Indent");
document.execCommand("Indent");
</script>
