Need a JS WYSIWYG editor that does NOT work on ContentEditable?

Question

JavaScript

We need an editor that would have the most identical behavior under all browsers. With ContentEditable, this is not possible, so the development of more or less complex plugins results in hellish torment. In general, the task is to insert monolithic interactive blocks (such as templates) into the text.
Don't offer TinyMCE and CKEditor. Everything is fine with the first one, but the ContentEditable disease makes itself felt. CKEditor does not have a clear API and documentation, so I did not even look.
