In our Facebook application running in Facebook's canvas environment the binding of scrollLeft and scrollTop methods fails with an "access denied" message in Internet Explorer 9. This causes completion of element binding to fail and breaks things pretty badly.

Facebook canvas apps exist in an HTTP POSTed cross domain iframe for security reasons to stop Facebook ids and access tokens getting linked and logged in access logs.

Here is the code that fails, starting at line 9348 in jquery version 1.8.2. I've added comments and a try catch around the line that fails, as that allows the function to complete, but obviously does nothing to add back the missing scrollTop / scrollLeft functions that haven't successfully bound.

   // Create scrollLeft and scrollTop methods
    jQuery.each( {scrollLeft: "pageXOffset", scrollTop: "pageYOffset"}, function( method, prop ) {
        var top = /Y/.test( prop );

        jQuery.fn[ method ] = function( val ) {
            return jQuery.access( this, function( elem, method, val ) {
                var win = getWindow( elem );

                if ( val === undefined ) {
                    return win ? (prop in win) ? win[ prop ] :
                        win.document.documentElement[ method ] :
                        elem[ method ];
                }

                if ( win ) {
                    win.scrollTo(
                        !top ? val : jQuery( win ).scrollLeft(),
                        top ? val : jQuery( win ).scrollTop()
                    );

                } else {
                    try {
                        // This line fails with "access denied" in an HTTP posted iframe in IE 9
                        elem[ method ] = val;
                    } catch (err) {
                        // do nothing. if this broke or there was an access denied bug for cross browser shenanigans,
                        // at least our element will continue to be created.
                    }
                }
            }, method, val, arguments.length, null );
        };
    });
