* Pulling in _editor_js.html is unnecessary - the only JS dependency that isn't in form media is now modal_workflow.js. (So close to being able to ditch the template override entirely!)

* Converts inline panel anchor to button to make keyboard focusable.
* Adds type='button' and undoes change to expanding_formset.js.
* Release notes for #7346
