A simple test case is this: {{{ a }}} Steps to reproduce: With the above content entered into the editor, set the cursor focus to be inside the unknown tag, then insert an image. Inside core/editable.js, the function {{{extractNodesData}}} throws an error trying to look-up the allowed names for this element. This is invalid HTML, so it is a user error, but the {{{config.allowedContent = true;}}} prevents it from being filtered out (as it should). We've seen it pop-up when users are copy and pasting content from other sources. So at a minimum, I think the editor should handle this case in some way. My suggestion is when {{{allowedContent}}} is set to true, the editor should treat all unknown tags as a semantically meaning-less tag, perhaps inheriting the {{{allowedNames}}} from {{{DIV}}} elements. I would be willing to submit a fix with the above suggestion, or implement another suggested fix if needed.
