When I rerender a component with "defaultChecked" or "defaultValue" react fails to update the "value" and "checked" attribute accordingly.

Before you say "use a controlled input" I would argue that this is a bug as it basically disallows uncontrolled forms with "reset" buttons. (It will always reset to whatever the initial default value was).

parentInfo = hostContainerInfo._ancestorInfo;
      }
      if (parentInfo) {
        
        
        validateDOMNesting(this._tag, this, parentInfo);
      }
      this._ancestorInfo =
        validateDOMNesting.updatedAncestorInfo(parentInfo, this._tag, this);
    }
    var mountImage;
    if (transaction.useCreateElement) {
      var ownerDocument = hostContainerInfo._ownerDocument;
      var el;
      if (namespaceURI === DOMNamespaces.html) {
        if (this._tag === 'script') {
          
          
          var div = ownerDocument.createElement('div');
          var type = this._currentElement.type;
          div.innerHTML = `<${type}></${type}>`;
          el = div.removeChild(div.firstChild);
        } else {
          el = ownerDocument.createElement(this._currentElement.type, props.is || null);
        }
      } else {
        el = ownerDocument.createElementNS(
          namespaceURI,
          this._currentElement.type
        );
