【问题描述】：
这个 Ionic3 (Angular 5) 项目必须从旧的 AngularFire 3.x 升级到 "@angular/fire": "^5.2.1"; 自那次升级以来，当使用设置为 iPhone/iPad 的“设备模式”在 Chrome 中运行应用程序时，会发生奇怪的行为。不会发生在 Android 模拟上。在某些时候（我无法识别），angularfire（我猜？）似乎在 body 元素中添加了一个 iframe：
<iframe ng-non-bindable="" frameborder="0" hspace="0" marginheight="0" marginwidth="0" scrolling="no" tabindex="0" vspace="0" width="100%"
id="I0_1562593422051"
name="I0_1562593422051"
src="https://XXXXXXXXX.firebaseapp.com/__/auth/iframe?apiKey=YYYYYYYYYYYYYY&appName=ZZZZZZZZZZZZZZZ&v=6.2.4&usegapi=1&jsh=m%3B%2F_%2Fscs%2Fapps-static%2F_%2Fjs%2Fk%3Doz.gapi.en_GB.4xsMIUspm18.O%2Fam%3DwQE%2Fd%3D1%2Frs%3DAGLTcCO_dMVTlnY55ZJNnloXSQJ2GsU_yw%2Fm%3D__features__#id=I0_1562593422051&_gfid=I0_1562593422051&parent=http%3A%2F%2Flocalhost%3A8100&pfname=&rpctoken=33463188" style="position: absolute; top: -100px; width: 1px; height: 1px;"></iframe>
尽管这在 firebaseapp.com 子域上完美运行，但 localhost（在 cordova 中使用）仅在 iOS 上遇到以下问题（不适用于 android，不适用于 chrome）...
欢迎任何建议，这是排除故障的第二天..！提前致谢。
一些不起眼的堆栈表明 core.js:1449 存在错误：
