We used to throw if event listener is not a function in Stack:

```js
ReactDOM.render(
  <h1 onClick={{}}>Hello World!</h1>,
  document.getElementById('container')
);
```

Fiber silently ignores this.

I think we should throw. This would let us add support for objects (e.g. for passive listener configuration) if we want to in a minor rather than a major.
inputValueTracking.track((domElement: any));
        ReactDOMFiberTextarea.postMountWrapper(domElement, rawProps);
        break;
      case 'select':
      case 'option':
        
        
        
        
        
        break;
      default:
        if (typeof rawProps.onClick === 'function') {
          
          trapClickOnNonInteractiveElement(((domElement: any): HTMLElement));
        }
        break;
    }
    return updatePayload;
  },
  diffHydratedText(textNode: Text, text: string): boolean {
    const isDifferent = textNode.nodeValue !== text;
    if (__DEV__) {
      if (isDifferent) {
        warnForTextDifference(textNode.nodeValue, text);
      }
    }
    return isDifferent;
  },
