V2 Back navigation, pages with dynamic content

Hi, during the back navigation, using router.back(url, options), I realized that the pages with a dynamic content, for example a page that contains a search bar and a result list, sometime lose the dynamic content (in this case the result list) and return the static html page only.

This behavior can depend on router page management strategy?

What is the best way to know if a page during the back navigation has lose his dynamic content?

Thanks 1k,
