[6.7.0 classic] After upgrade 6.6.0 to 6.7.0 app crashes in Internet Explorer 8

[artray]

Production built app crashes with error: "SVGElement is undefined" in IE8.
The problem is caused by a change in Ext.dom.Element's replaceCls method.

Towards the end of the function in 6.6.0.285 there is:

else if (added) {
    me.dom.className = list.join(' ');
}

Which was changed in 6.7.0.166 to:

else if (added) {
    list = list.join(' ');


    if (dom instanceof SVGElement) {
        // dom.className is an instance of SVGAnimatedString
        // for SVG elements. Setting the `class` attribute
        // of an SVG element will update its `dom.className.baseVal`.
        dom.setAttribute('class', list);
    }
    else {
        dom.className = list;
    }
}

If you add a check for Internet Explorer 8 or lower the problem is solved:

else if (added) {
    list = list.join(' ');


    if (!Ext.isIE8m && dom instanceof SVGElement) {
        // dom.className is an instance of SVGAnimatedString
        // for SVG elements. Setting the `class` attribute
        // of an SVG element will update its `dom.className.baseVal`.
        dom.setAttribute('class', list);
    }
    else {
        dom.className = list;
    }
}
