bug: ion-router-outlet does not show correct page after vue-router navigation guard was used #29721

Prerequisites

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

Ionic Framework Version

v8.x

Current Behavior

The ion-router-outlet shows the wrong page after a vue-router navigation guard was used.

Given:

• ion-page Home
• ion-page Register
• ion-page Profile

When:
A user registers using the following flow: Home -> Register -> Profile.
The transition from Home -> Register uses router.push.
The transition from Register -> Profile uses router.replace.
Being on the Profile page, back navigation is prevented using a navigation guard (see example).

Then:
After a logout (Profile -> Home), it's not possible to log in again (Home -> Profile) because the ion-router-outlet shows the wrong page although the path was changed to /profile.

Expected Behavior

The correct ion-page should be displayed after a navigation guard prevented the user from going back.

The Profile page should be displayed.

Steps to Reproduce

1. go to Home page
2. click on "REGISTER"
3. click on "SIGN UP"
4. try to go one step back in history, e.g. by using the back button on the mouse
5. see that the page does not change [EXPECTED]
6. click on "LOGOUT"
7. click on "LOGIN"
8. see that page does not change [BUG]
