Rendering a <textarea> in the backend and then calling $(...).richEditor() gives the following error:
TypeError: null is not an object (evaluating ‘this.options.editorOptions.constructor’)
Context: I want to render a custom modal window in my plugin that gets placed before the </body> tag when clicking a specific element in the richeditor field. The textarea inside the modal needs to become a richeditor too, same as the all the others.
