insertElement closes previous tag, inserts new element, and reopens tag

In IE11 and FF (at least), using insertElement closes and reopens tags if the cursor is inbetween a tag such as   <P>Sample *cursor* Text</P>

Expected:  <P>Sample <div class="A"></div> Text</P>

Actual:  <P>Sample </P><div class="A"></div> <P>Text</P>

Code from custom plugin:

                    onOk: function () {

                        var div = CKEDITOR.dom.element.createFromHtml('<div class="A"></div>', editor.document);

                        editor.insertElement(div);

                    }

What is the proper way to insert an element without affecting surrounding HTML?   Using 4.3.3
