Javascript $sceDelegateProvider资源url白名单无效

HTML:

在fiddle之外执行上述操作时，控制台中出现以下js错误：

Error: [$interpolate:noconcat] http://errors.angularjs.org/1.5.6/$interpolate/noconcat?p0=https%3A%2F%2Fwww.google.be%2Fsearch%3Fq%3D%7B%7Bquery%7D%7D

其中链接导致以下解释：

Error while interpolating: https://www.google.be/search?q={{query}}
Strict Contextual Escaping disallows interpolations that concatenate multiple expressions when a trusted value is required.  See http://docs.angularjs.org/api/ng.$sce

这很奇怪，因为我把“**”列为白名单，我的小提琴就证明了这一点

为什么白名单没有任何效果？

我认为ng src与$sce不兼容。在fiddle works中将ng src更改为ng bind html

  <iframe ng-bind-html="https://www.google.be/search?q={{query}}"></iframe>

这确实会显示正确的html，但iframe根本不会呈现。我尝试使用{{query}}，这实际上是测试iframe的更好的页面。google one永远不会在iframe中渲染。
