    // information on the fiber.
    //
    // That's why this function is separate from pushTreeId — it's called during
    // the render phase of the fork parent, not the child, which is where we push
    // the other context values.
    //
    // In the Fizz implementation this is much simpler because the child is
    // rendered in the same callstack as the parent.
    //
    // It might be better to just add a `forks` field to the Fiber type. It would
    // make this module simpler.
