bug: routing with angular [queryParams] breaks subsequent relative navigations

• I agree to follow the Code of Conduct.
• I have searched for existing issues that already report this problem, without success.

Ionic Framework Version

• v4.x
• v5.x
• v6.x

Current Behavior

With Angular, when using ion-router-outlet as navigation root, relative navigation breaks if we use [routerLink] with a relative route combined with any [queryParams] value. After the first one, all other relative routes would not trigger navigation anymore.

Expected Behavior

The ion-router-outlet should behave like the angular's router-router : relative navigation is still possible once we navigated with query params.

Steps to Reproduce

I made a simple repro : https://stackblitz.com/edit/ionic-angular-v5-xjfgnp?file=src/app/dummy.component.ts
You can switch from Ionic to Angular router outlet using the top toggle button.

Once you click on the second link Stay on route 1 with query params with ion-router-outlet, relative navigation to other routes is broken and 3rd link will not trigger navigation anymore.

The same actions with Angular router-outlet would still work.

@adeprez thanks for reporting this issue!

I see that when using ion-router-outlet and routing to a route with query parameters, the other router link href is being updated to /. This behavior is inconsistent with router-outlet, where the router link is untouched when navigating to a route with query params.

We will log this issue as a bug and prioritize, thanks!

I have experienced this issue today and have resorted to remove query params and solve the route params using a different method (storage). Seems to work fine in web but not on tablets and phones, at least in the emulated ones. I have updated to 6.0.7 and still had the issue.
