Describe the Bug

When using cloneElement in a React component, passing anything to the optional props parameter causes the children of the cloned element to not render.

Here's a screenshot of the DOM rendered in the linked StackBlitz example. Notice that the div of the ClonedWithProps component is rendered but not it's children, while the ClonedWithoutProps children are rendered correctly.

The only difference between the two components is that one calls cloneElement(element, props) while the other only calls cloneElement(element)

Looks like React doesn't like passing null or undefined as the children prop is the reason.
