*Bug*

When a `textarea` has the `required` attribute it renders in the invalid state using FireFox. 

This behavior is visible here: https://codesandbox.io/s/rough-frog-f00ow. Remember to view it in FireFox.  

I expect the required field to validate on form submit and not before. 

I have tested this with FireFox 68 and 69 and React 16.8.6

This appears appears to be a re-occurrence of: https://github.com/facebook/react/issues/8395


const node = ((element: any): TextAreaWithWrapperState);
  
  
  const textContent = node.textContent;
  
  
  
  
  if (textContent === node._wrapperState.initialValue) {
    node.value = textContent;
  }
}
export function restoreControlledState(element: Element, props: Object) {
  
  updateWrapper(element, props);
}
