   This function is copied from React and should be kept in sync:
   https:github.com/facebook/react/blob/main/packages/react-reconciler/src/ReactFiberTreeReflection.js
   It would be nice if we updated React to inject this function directly (vs just indirectly via findDOMNode).
   BEGIN copied code
  function findCurrentFiberUsingSlowPathById(id: number): Fiber | null {
    const fiber = idToArbitraryFiberMap.get(id);
    if (fiber == null) {
      console.warn(`Could not find Fiber with id "${id}"`);
      return null;
    }
    const alternate = fiber.alternate;
    if (!alternate) {
       I
      const state = isFiberMountedImpl(fiber);

        throw Error('Unable to find node on an unmounted component.');
