Open-source WYSIWYG editors: not quite there yet?

I'm looking for a free HTML editor suitable for end-users that are less comfortable entering html in a textarea. The most advanced open-source projects that fit this description seem to be xinha, a fork of the discontinued HTMLArea, and FCKEditor. Both suffer from problems with corrupting the browser history; bug reports are here and here (and here too). I note though that blogger's proprietary editor doesn't have this problem.

Breaking my back button is a serious usability problem. I note that both of these projects have huge amounts of features, far more than Blogger does. This would actually be a drawback to me if I were to deploy one, since I'd have to figure how to turn all the bloat off. Perhaps a project that focused less on features and more on usability could succeed better here.

(Please, if there's one out there that I missed, point me to it.)
