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

Start with the Mouse and pointer events section at the linked accessibility documentation and reproduce the behavior using the provided CodePen. Read the linked MDN focus-event reference to verify the event behavior. Done means the example is corrected so the documented interaction works, or the issue is closed if the reported behavior is mistaken.
