title: ERROR: Expected to not be in Angular Zone, but it is
body: <p>I was trying to build a demo by using Angular and single-spa to see whether this could be our future path of development. Here is the example I tried to borrow from.</p>

  <p>However, I found when routing to another application, for example: click on Open Help or App1, the console will have errors like "ERROR: Expected to not be in Angular Zone, but it is!"</p>
  
  <p>I did some research on internet trying to fix this error. However, I didn't found solution. I also submited an issue to the project. I'm just wondering whether anyone knows anything about this error here.</p>
  
  <p>Thank you in advance!</p>
