Thank you for the sent sample. I can replicate the problem in my local end.
I will have this forwarded to the development team to be investigated further.

Thank you and have a nice day.

I found that whenever node is pulled from the DOM tree, the contentWindow is set to null, forcing a reload of the iframe’s content. The same thing happens on WebTextEditor where the content editor uses iframe element. This problem was caused by browser not WebTextEditor.

I’d like to suggest you a workaround. The bottom line is that to avoid losing the state of an iframe, you must not detach it or one of its ancestors. If only _rtbDiv contained an iframe and you wanted to move it before _firstChildDiv (which wouldn’t contain an iframe), then you could move _firstChildDiv after _rtbDiv instead of moving _rtbDiv before _firstChildDiv.

Following snippet code shows how to implement this by modifying click2 and moveItem function.

function moveItem(toMoveId, newPrecedingItemId)
{
    var toMove = document.getElementById(toMoveId);
    var newPrecedingItem = newPrecedingItemId ? document.getElementById(newPrecedingItemId) : null;
    if (toMove.insertAdjacentElement)
    {
        if (newPrecedingItem != null)
        {
            if (newPrecedingItem == toMove)
                return;
            newPrecedingItem.insertAdjacentElement("beforeBegin", toMove);
            //newPrecedingItem.insertAdjacentElement("afterEnd", toMove);
            return;
        }
        document.getElementById("_parentDiv").insertAdjacentElement("afterBegin", toMove);
        return;
    }
    var containerDiv = newPrecedingItem ? newPrecedingItem.parentNode : document.getElementById("_parentDiv");
    var followingItem = newPrecedingItem ? newPrecedingItem.nextSibling : containerCell.firstChild;
    if (followingItem)
    {
        containerDiv.insertBefore(toMove, followingItem);
        return;
    }
    containerDiv.appendChild(toMove);
    return;
}
function click2()
{
    moveItem("_lastChildDiv", "_rtbDiv");
    //moveItem("_rtbDiv", "_lastChildDiv");
    return false;
}

Please let me know if you have other thought.

Since the reported problem was not caused by WebTextEditor, we will treat this as enhancement. The development team still working on this case, but I’m afraid that the enhancement will take time longer.

Thank you and have a nice day.
