### Ionic Framework Version

v8.x

### Current Behavior

App with routes outside tabs:
when you navigate to a route outside the tabs the ion back button works great, but using the swipe back animation doesnt show the previous page for a moment (works in ionic angular).
In the video you can see on the first try going back using the back button and then using a swipe

### Expected Behavior

Going back using the back button or by using the swipe back should work the same

### Steps to Reproduce

set app to mode "ios"

### Additional Information

_No response_

Start with the linked StackBlitz reproduction and its src/App.tsx in iOS mode. Compare the back-button and swipe-back transitions when navigating from tabs to an outside route. Done means both navigation methods show the previous page consistently during the back animation.
