Pasting into ice is broken in webkit. This was referenced in #18.

The logic one has to use as far as I know it:
IE/Firefox: one wait for the paste to happen, then cleans up the element, (moves it to the main edit window)
Webkit: one cancels the paste event, copies the clipboard data, cleans it, inserts it

like this:

function handlePaste(e) {
if (e && e.clipboardData && e.clipboardData.getData) { // Webkit: we cancel the paste event, copy clipboard data, clean it, insert it
    e.stopPropagation();
    e.preventDefault();
    if (notRecentlyPasted) {
        notRecentlyPasted = false;
        setTimeout(function () {
            notRecentlyPasted = true;
        }, 1)
        var pasteElement = document.createElement('div');
        if (/text\/html/.test(e.clipboardData.types)) {
            pasteElement.innerHTML = e.clipboardData.getData('text/html');
            removeExtraFormatting(this, pasteElement);

        } else if (/text\/plain/.test(e.clipboardData.types)) {
            pasteElement.innerText = e.clipboardData.getData('text/plain');
        }

        addPasteContents(pasteElement);
        addZombieBR();
        return false;
    }
} else { // IE/Firefox - we wait for the paste to happen, then clean up the entire element
    var oldLength = this.innerHTML.length;
    waitForPaste(this, oldLength);
    return true;
}
}

@delambo Are you working on this right now?

I will work on this sometime in the next couple of weeks. The following is the best cross-browser paste solution that I have tried:

1. detect ctrl/cmd-v keypress event
2. set a bookmark in the editor
3. create a temporary, hidden div element and focus the selection/range into it
4. set a brief timeout (defer) with a handler that fires after the browser pastes into the div created in (4)
5. With the handler created in (5), grab the paste from the div, clean it, then insert it into the body at the bookmark

The biggest drawback is that the context/app menu pastes don't work.

I see. Yes, I thought that only works in Firefox/IE, and that in Webkit you need to use the above method. But I may be wrong.
