Hi, few days ago I was trying to embed a date picker in my Elm app. I have used MutationObserver, so in Elm all I have to do is to add a specific class and custom event handler, so there is no need to track it by "id". The mutation observer is attached at the top node of the Elm app. This works OK so far.
I have described it here: https://www.reddit.com/r/elm/comments/5uqa13/those_fancy_date_pickers_in_elm_watch_this_no/ There is also a demo app. I was wandering if I could use exactly same approach to embed a rich text editor. I wanted to check it out and publish my results, but did not have time to do it yet. What kind of editor are you using? What exactly is your "content" value, "Overlay.editedValue" and "markdownView" functions doing?
