In CKEditor 4.1, Image bookmarks are rooted to the documentElement (see CKEDITOR.dom.element::getByAddress). This is probably fine if the editor is in an iframe, but problematic if the 'divarea' plugin is enabled. If an element is inserted before the editor, the selection will be placed in the wrong position (or get an error) when invoking undo. To reproduce: 1. copy attached sample into samples folder. 2. Open it in browser. 3. Delete character with backspace 4. Wait 500ms and press Undo Result: Error is thrown - IndexSizeError: Index or size is negative or greater than the allowed amount. Problem can be reproduced from CKEditor 4.0 beta. ",Bug,confirmed,Normal,,Core : Selection,4.0 Beta,,,
