Safari のプライベートブラウズだと LINEログイン出来ない

1. 使用技術

Spring Boot Starter Security 2.7.1

2. 原因

Safariのプライベートブライズモードだと、タブ毎にCookie管理を行なっている（はず。。）。
よって、別タブに切り替えるとログインしているSessionの情報を保存している Cookie が無くなる。

LINEログインをした後に、LINEの認可サーバーが別タブでレスポンスを返却する。

そのため、Cookie が消失して、ログインエラーとなる。

3. 備考

3-1. 備考1

LoggerのレベルをTRACEにすると、下記のようなエラーが出る。
****は、省略。
OAuth2LoginAuthenticationFilterを呼び出す際に、Cookie を消失しているので認可リクエストを取得出来ない模様。
