Integrate Single-SPA with Multiple Angular Applications and Configure RouteReuseStrategy

[karanmobilesentrix]

We have integrated a single-spa microfrontend architecture to host multiple Angular applications. Each Angular project has been configured with a custom RouteReuseStrategy to support Back/Forward Cache (bfcache) functionality.

The reuse strategy works as expected within individual Angular applications. However, when navigating from one Angular application to another through single-spa, the RouteReuseStrategy does not behave correctly and the state is not preserved.

Steps to Reproduce:

• Navigate within an Angular app — Back/Forward Cache works as expected.
• Navigate from App A to App B (both hosted via single-spa).
• Attempt to go back — the state is not restored as intended.

Expected Behavior:
State should be preserved across navigation between different Angular apps using the configured RouteReuseStrategy.
