Currently, component updates are being ignored

/** @internal */
public shouldComponentUpdate(nextProps, nextState) {
  return !SERVER_RENDERED
}

This means that any update to event handlers just straight up don't work.

In this example, regardless of any calls to setValue, whenever a key is pressed, only the first function passed to CodeMirror is called.

const component = () => {
  const [value, setValue] = useState("old value");
 
  const handleKeyPress = () => {
    console.log("key pressed - value is", value);
  }

  useEffect(() => {
    setValue("new value")
  }, []);

  // ...
  onKeyPress={handleKeyPress} // The new function is ignored on second render
  // ...
}

Edit: Looks like the issue in this case is due to the way SSR is being detected - I'm trying to use this inside a chrome devtools extension.

Edit 2: Nothing to do with a chrome extension... I've created a PR 👍
