in "block-level" widgets (divs), when hitting [return] instead of adding a newline in the widget a new bit of widget may be added. This is caused by an incompability between widgets and the enterKey plugin. Remove enterKey, behavior on [Return] is slightly worse (always inserts br) but widgets don't get broken. See https://dev.ckeditor.com/ticket/11326 for issue in upstream. bzr revid: xmo@openerp.com-20131217153751-7fbwp34o8kac9x94
