When pressing keys in our composite component showcase in IE we are getting a popup "Message from webpage" "Out of memory at line: 140".

The Developer Tools javascript debugger breaks with an Out of memory error in the following code:

<span id="debugPanel"><script language="javascript" type="text/javascript">//<![CDATA[
function faceletsDebug(URL) { day = new Date(); id = day.getTime(); eval("page" + id + " = window.open(URL, '" + id + "', 'toolbar=0,scrollbars=1,location=0,statusbar=0,menubar=0,resizable=1,width=800,height=600,left = 240,top = 212');"); };var faceletsOrigKeyup = document.onkeyup; document.onkeyup = function(e) { if (window.event) e = window.event; if (String.fromCharCode(e.keyCode) == 'S' & e.shiftKey & e.ctrlKey) faceletsDebug('/component-showcase/showcase.jsf?facelets.ui.DebugOutput=1294359175693'); else if (faceletsOrigKeyup) faceletsOrigKeyup(e); };
//]]>

And highlights faceletsOrigKeyup(e)

Once I commented out <ui:debug hotkey="s" rendered="true"/>, the error no longer occurred.
