Which @angular/* package(s) are the source of the bug?

router

Is this a regression?

No

Description

When withExperimentalPlatformNavigation() is enabled in app.config.ts, the ng serve --live-reload=true functionality breaks.

Making changes to source files triggers a rebuild in the terminal, but the browser does not refresh. Removing withExperimentalPlatformNavigation() restores expected live-reload behavior.

Please provide a link to a minimal reproduction of the bug

Please provide the exception or error you saw

## Expected Behavior

The browser should automatically reload when files are changed, regardless of whether the native navigation integration is enabled.

## Actual Behavior

The browser fails to reload. It appears the connection to the live-reload socket is maintained, but the trigger to refresh the page is either blocked or ignored by the Navigation API integration.

## Exception or Error

No error is printed in the browser console, but the refresh simply does not occur.
