getParentElement() is not working in Edge

[Sachita]

Hi Team,

I am getting console issue with getParentElement(),this shows element value as null

which affects all other functionalaities.

 function RadEditorElementDesignerModule(element) {
                    RadEditorElementDesignerModule.initializeBase(this, [element]);
                };

                RadEditorElementDesignerModule.prototype =
                {
                    initialize: function() {
                        RadEditorElementDesignerModule.callBaseMethod(this, 'initialize');
                        var selfPointer = this;
                        this.get_editor().add_selectionChange(function() { selfPointer.doSomething(); });
                        this.doSomething();
                    },
                    doSomething: function() {
                        var module = this.get_element();
                        Test.$('RadEditorElementDesignerModule').setInnerHTML('').hide();
                      
                        var selection = this.get_editor().getSelection();
                        
                        var element = selection.getParentElement();
                        if (element.designer) {
                       
                           if (designers[element.designer]) {
                                try {
                                    designers[element.designer](element, module);
                                    BDS.$('RadEditorElementDesignerModule').show();
                                }
                                catch (ex) { }
                            }
                        }
                    }
