How to make the route multiplexing policy effective in asynchronous routing?

RouteReuseStrategy not fully working with lazy loading ngModule

The
project uses a route reuse strategy, and the effect is good. When you switch routes, the previous route snapshots are loaded, which makes it a good experience for pages that fill in classes such as forms. however, in the case of lazy loading routing, route multiplexing does not take effect. Is there any friend who has encountered such a situation and solved it?
