     * Gets the instance type for a React element. The instance will be different for various component types:

     * - React stateless functional components do not have a backing instance and so `React.ElementRef<typeof Bar>`
     *   (when `Bar` is `function Bar() {}`) will give you the `undefined` type.
     * - JSX intrinsics like `div` will give you their DOM instance. For `React.ElementRef<'div'>` that would be
     *   `HTMLDivElement`. For `React.ElementRef<'input'>` that would be `HTMLInputElement`.
     * - React stateless functional components that forward a `ref` will give you the `ElementRef` of the forwarded
     *   to component.
     *
     * `C` must be the type _of_ a React component so you need to use typeof as in React.ElementRef<typeof MyComponent>.
     *
     * @todo In Flow, this works a little different with forwarded refs and the `AbstractComponent` that
     *       `React.forwardRef()` returns.
