Collapsible section inside tab layout doesn't work for IE 8



When Tab layout contains multiple collapsible section and when user collapses a section, section is collapsed but IE8 leaves an empty area.  Also, when expanding a section, the expanded section is displayed above the collapsible section below in Internet Explorer version 8 (IE 8).  IE 8 does not move collapsible sections inside Tab layout on collapse/expand actions.

This issue is been resolved by adding the following code into UserWorkForm section.

pega.ui.Doc.prototype.expandHeader = function(expandElement, event, container, bFromKeyboard) {
                  event = event || window.event; 
        var target = pega.util.Event.getTarget(event);
        if(bFromKeyboard && event.keyCode != 32 && event.keyCode != 13)
        if (!target.tagName.match(/^(input|select|textarea|button|a)$/gi)) {
             /* Code to handle icons */
            if(target.tagName.toLowerCase() == "i" || target.tagName.toLowerCase() == "img") { /*BUG-158775: Stopping icons/controls present on the header from expanding/collapsing the header on click.*/
                if(target.getAttribute("data-ctl") && target.getAttribute("data-ctl") == "Icon") {
            if (container) {
                this.loadContainer(expandElement, event, container);
            } else {
                this.expandIt(expandElement, event);
            this.setARIAAttributesForHeader(expandElement, event);
