Uncaught TypeError: (intermediate value)(...) is not a function

[li8]

When I initialize the codemirror editor in my application , I get

    Uncaught TypeError: (intermediate value)(...) is not a function

On further testing , I found that the issue only persisted while loading the elm mode.
You can check it out here : https://codemirror.net/demo/loadmode.html
On changing the file extension to 'elm', the error is shown in the console.

In my application , this error becomes a blocker. After this error pops up , the CodeMirror Editor stop loading any mode at all. I have tested it on other applications, it gives the error for elm but still continue to work.

Thank you @marijnh . I just figured out the same thing- the extra parentheses.
