contentRef is passed to EventStack to subscribe for mouse events. Passing a `contentRef` created using `React.createRef()` does not allow EventStack to keep track of contentRef changes (since only contentRef.current changes). Ultimately when PortalInner unmount contentRef.current is set to undefined and EventStack `unsubscribe` handlers with `undefined` as a target instead of unsubscribing with real content. This leads to the event-stack Map keeping a reference to the real contentRef thus leaking all dom tree related to the node related to contentRef. Putting contentRef in the state and passing the element allow for EventStack to detect change in props and execute the componentDidUpdate routine which unsubscribe from the previous element on unmount.
