在 iOS 15+ 上的 PWA 中設置 window.location 失敗以獲取身份驗證體驗

Question

我目前正在構建一個網站，該網站提供使用 Facebook 登錄作為讓用戶在我自己的身份系統中進行身份驗證的方法，並且它在所有平台上的普通瀏覽器中運行良好。 But when I install it as PWA on iOS 15+, the Facebook login is not functioning as expected as the webView is not honoring the window.location=<MY OWN CALLBACK URL TO MY SERVER> . Below are the scripts from my server that's handling the callback from Facebook, seems both window.opener.location and window.location setting failed because the popup window was closed but nothing happened in the opener.

<script type="text/javascript">
    var redirectUri = '${myApp() + "/login?"}';
    redirectUri = redirectUri + "access_token=" + "${access_token?no_esc}" + "&token_type=fb";
    redirectUri = redirectUri + "&_eventId=loginFromFacebook";
    

    if ( window.opener ) {
        window.opener.location = redirectUri;
        self.close();
    }

    window.location = redirectUri;

</script>
