Invalid Example for Mouse and pointer events Documentation

Hi, I think here is Invalid example for this documentation

https://reactjs.org/docs/accessibility.html#mouse-and-pointer-events

In this documentation, there is a code not to close the pop-over when focusing on the child.

// If a child receives focus, do not close the popover.
onFocusHandler() {
  clearTimeout(this.timeOutId);
}

but, when i click child element, child element doesn't receive focus
so when i click child element, the pop-over closes.

CodePen

I think it's because of onFocus event does not bubble.

https://developer.mozilla.org/en-US/docs/Web/API/Element/focus_event

This example is likely to cause confusion. How about modify the example to make it work?

If I'm mistaken, I think This issue may well be closed.

thanks

Comienza con la sección Mouse and pointer events de la documentación de accesibilidad enlazada y reproduce el comportamiento usando el CodePen proporcionado. Lee la referencia de MDN enlazada sobre focus-event para verificar el comportamiento del evento. La tarea estará terminada cuando el ejemplo se haya corregido para que funcione la interacción documentada, o cuando se cierre el issue si el comportamiento informado es erróneo.
