prevent contenteditable mode from creating tags

Question

When I use the browser contenteditable=true on a div in order to let the user update the text in it, I run into this problem (using Chrome):

When using the delete

The problem is, actually, that not only it inserts span's and p's, but if you happen to copy a table it will insert the whole table with tbody and rows there. So, the only option to handle this that I've found working for me is this:

$(document).on("DOMNodeInserted", $.proxy(function (e) {
        if (e.target.parentNode.getAttribute("contenteditable") === "true") {
            with (e.target.parentNode) {
                replaceChild(e.target.firstChild, e.target);
                normalize();
            }
        }
}, this));

Yes, it somewhat affects the overal page performance, but it blocks inserting tables and stuff into the contenteditables.

UPDATE:
The script above handles only basic cases, when the content you wish for is wrapped in one level of span/p tags. However, if you copy from, say, Word, you may end up copying even the whole tables. So, here is the code that handles everything i've thrown at it so far:

$(document).on("DOMNodeInserted", $.proxy(function (e) {
    if (e.target.parentNode.getAttribute("contenteditable") === "true") {
        var newTextNode = document.createTextNode("");
        function antiChrome(node) {
            if (node.nodeType == 3) {
                newTextNode.nodeValue += node.nodeValue.replace(/(\r\n|\n|\r)/gm, "")
            }
            else if (node.nodeType == 1 && node.childNodes) {
                    for (var i = 0; i < node.childNodes.length; ++i) {
                        antiChrome(node.childNodes[i]);
                    }
            }
        }
        antiChrome(e.target);

        e.target.parentNode.replaceChild(newTextNode, e.target);
    }
}, this));

Also, feel free to modify the regex in the middle any way you like to remove symbols that are particularly hazardous in your case.

UPDATE 2
After thinking for a little while and googling, I've just wrapped the code above into simple jQuery plugin to ease the usage. Here is the GitHub link
