Describe the Bug
Navigation is stuck after navigating between two components with child routes and ion-router-outlets. This works in angular with router-outlet but not after IonicModule is imported.

Steps to Reproduce
Steps to reproduce the behavior:

1. Go to https://ion-router-outlet-bug.stackblitz.io/first/tab1
2. Click through Tab 1 - 3 and see the content change.
3. Click "Second Tabs Page"
4. Click through Tab 4 - 6 and see the content change.
5. Click "First Tabs Page" (navigating you back)
6. The content is now stuck to the last tab you clicked.

Expected Behavior
Navigation should still work after navigating from /first to /second

The docs states that should behave as angular's
