複数ライバルの比較が動いていない

トップページの ライバル: のtextboxのplaceholderに User ID,User ID,User ID,... とあり複数比較ができるように見えるのですが、動作しません。
ライバルの欄を空白(あるいは存在しないユーザを入れたとき)と同様の挙動をします。
例: http://kenkoooo.com/atcoder/?name=kimiyuki&rivals=kenkoooo%2Cchokudai&kind=index

(元々未実装でなくて) バグならば修正をお願いしたいです。

[Suggestion] Matching the typescript model definition to API returned data structure

In ApiCall.tsx, the function returns the array of the model. It seems the returned API data structure and the typescript models are very similar. How about matching typescript models to the returned API data structure?

For example, getSubmissions function can be simplified like this.

  static getSubmissions(
    url: string,
    query?: { user: string; rivals: string }
  ): Promise<Array<Submission>> {
    return this.getJson(url, query).then((obj: Array<any>) => {
      let submissions: Submission[] = obj.map(o => o as Submission);
      return submissions;
    });
  }

This does not work for getRanking and getRatedPointSumRanking since these functions treat some of the returned properties as something else.

Matching enables shorter code and less maintenance. Currently, if we change the properties in the models, we have to edit corresponding API call using that model. Also, some of the property must be changed from camel case to underscores such as contestId and userId unless there are specific reasons for using camel case. I believe the above example should work, but let me know if it doesn't work.
