我正在尝试在 FB Instant 文章中嵌入我自己的脚本（注入带有一些内容的 iframe）。
它似乎仅适用于某些设备（例如 iPhone 5s 和 6s、LG G2），但其他设备（三星设备）似乎没有加载任何内容。
显然问题在于对脚本的 src 提出实际请求，但这只是一个假设。（我已将 src 更改为 angular 以进行演示）。
我尝试使用 Facebook 在此处建议的工具进行调试：链接
我添加了我的页面示例（仅供参考，如果您将其粘贴到文章编辑器中，它将引发警告）。
注意：当我的代码在没有来自某个来源的请求的情况下直接插入脚本标签时，它会按预期运行。
有什么问题？为什么 FB Instant Articles 不调用我的脚本？
谢谢

<p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker <a href="http://www.lipsum.com/">including versions of Lorem Ipsum.</a>)</p>
