### How often does this bug happen?

Every time

}
   We use this to simulate unmounting for Suspense trees
   when we switch from primary to fallback.
  function unmountFiberChildrenRecursively(fiber: Fiber) {
    if (__DEBUG__) {
      debug('unmountFiberChildrenRecursively()', fiber);
    }
     We might meet a nested Suspense on our way.
    const isTimedOutSuspense =
      fiber.tag === ReactTypeOfWork.SuspenseComponent &&
      fiber.memoizedState !== null;
    let child = fiber.child;
    if (isTimedOutSuspense) {
       If 
      const primaryChildFragment = fiber.child;
      const fallbackChildFragment = primaryChildFragment
        ? primaryChildFragment.sibling
        : null;
       Ski
      child = fallbackChildFragment ? fallbackChildFragment.child : null;
    }
    while (child !== null) {
       Rec
       We 
      if (child.return !== null) {
        unmountFiberChildrenRecursively(child);
        recordUnmount(child, true);
      }
      child = child.sibling;
    }
