 Hi,
 I found an issue with the core code.

 It is mentioned on this link that the CodeMirror lib will support JSX by
 default in the editor.
 https://make.wordpress.org/core/2017/10/22/code-editing-improvements-in-
 wordpress-4-9

 But when I use JSX mode, I do see an invalid System error in the editor.

 Please see this image:

                 indentUnit: 2,
                 tabSize: 2,
                 mode: 'jsx'
             }
