I believe you used setTimeout as a workaround to ensure that the state is updated.
Although it works, it may be better to transform the handleSuccess function into a Promise, to make this state update guarantee better.
Can you test whether removing setTimeout and changing handleSuccess to a Promise works well?

  private handleSuccess = (id: string) => {
    return new Promise<void>((resolve) => {
      this.setState(({ completed }) => {
        completed.push(id);
        return { completed };
      }, resolve);
    });
  }
