How to select html tags with their contents when using selectNodeContents?

I have this bit of code that I use to get the cursor position in an editable div:

   function getMeCurPos(element){
       if (typeof window.getSelection != "undefined") {
          var range = window.getSelection().getRangeAt(0);
          var preCaretRange = range.cloneRange(); 
          preCaretRange.selectNodeContents(element);
          preCaretRange.setEnd(range.endContainer, range.endOffset); 
          caretOffset = preCaretRange.toString().length;  
          return caretOffset;
       }                        
   }

The problem is that the caretOffset function returned only the amount of text content, not the html tags. For instance,

Consider this line in my editable div: Hey <b>jony</b>, whats goin on in the | party

* The cursor is indicated by |.

Running getMeCurPos (ele) returns: 30but it should return 37. It does not count tagsb

: DIV

            <script type="text/javascript">

                    if (document.selection) {
                        var range = document.body.createTextRange();
                        range.moveToElementText(document.getElementById(containerid));
                        range.select();
                    } else if (window.getSelection) {
                        var range = document.createRange();
                        range.selectNode(document.getElementById(containerid));
                        window.getSelection().addRange(range);
                    }
                }
            </script>

            <div id="selectable" onclick="selectText('selectable')">http://example.com/page.htm</div>

You can use cloneContents()Javascript in the selection range to get the selection both in text and as DOM nodes . HTML as below

function getMeCurPos(element) {
  if (typeof window.getSelection != "undefined") {
    var range = window.getSelection();
    cloned.innerHTML = '';
    for (let i = 0; i < range.rangeCount; i++) {
      cloned.append(range.getRangeAt(i).cloneContents());
    }

    var sanitized = cloned.innerHTML;
    caretOffset = sanitized.length;
    return caretOffset;
  }
}
<p contenteditable="true" id="test" onclick="alert(getMeCurPos(this))">Test1<br>Test2<br>Test3<br>Test4</p>
<br>
Cloned: <span id="cloned"></span>
Run code
