ThrottleFirstFrame throws NullReferenceException

[hsanno]

ThrottleFirstFrame throws NullReferenceException when stream sends OnNext immediately.
Could you allocate tick before subscribing?

// ThrottleFirstFrame.Run
public IDisposable Run()
{
    cancelable = new SerialDisposable();
    // if source sends OnNext immediately, tick is null!
    var subscription = parent.source.Subscribe(this);

    tick = new ThrottleFirstFrameTick(this);

    return StableCompositeDisposable.Create(cancelable, subscription);
}
