Angular 11 Warning "google-maps-autocomplete contains deep imports into …"

After upgrading to Angular 11 and google-maps-autocomplete 0.6: Every time I build my project I get the following warning:

```
[ANGULAR] Warning: Entry point '@angular-material-extensions/google-maps-autocomplete' contains deep imports into '/…/node_modules/rxjs/internal/Subject'. This is probably not a problem, but may cause the compilation of entry points to be out of order.
