How to use React.cloneElement with TypeScript?

I have the component that renders the content of the tab. It simply detects if children is only child and if not it wraps them in div. It also can (optionally) apply prop with styles by cloning the child. I wrote this component many months ago, then I updated some libraries and TypeScript. Today I am watching its code and I see errors.

The component

import * as React from 'react';

export interface PageTabContentShape {
  title: string;
  pageTabName?: string;
  withContainer?: boolean;
  containerStyle?: React.CSSProperties;
  labelTestid?: string;
  children: React.ReactElement;
}

export const PageTabContent: React.ComponentType<PageTabContentShape> = (props) => {
  let child = React.Children.only(props.children);
  if (props.withContainer) {
    return (
      <div style={props.containerStyle}>
        {child}
      </div>
    );
  }
  // pass styles to only child when there is no wrapper
  if (props.containerStyle && React.isValidElement<{ containerStyle }>(child)) {
    child = React.cloneElement(child, { containerStyle: props.containerStyle });
  }
  if (null != child) {
    return child;
  }
  return null;
};

Errors:

Argument type ReactElement<{containerStyle}> is not assignable to parameter
type DetailedReactHTMLElement<HTMLAttributes<HTMLElement>, HTMLElement> 

and

Argument type {containerStyle: React.CSSProperties} is not assignable to parameter
type HTMLAttributes<HTMLElement> | undefined 

Place of the errors:

I tried different approaches, adding null checks and returning early with null, adding type assertions as ReactNode or as ReactElement. But I can't make TypeScipt choose another definition of the cloneElement method which I see in index.d.ts of @types/React

Question

How can I properly declare this component to make TypeScript errors vanish? If it is possible I would like to do it without types assertion. If it is possible I need to do it without any NPM updates (might consider minor update).

Packages in use:

• "@types/react": "16.9.1",
• "react": "16.9.0",
• "typescript": "3.8.2",
