RouteNormalizerRequestSubscriber redirects away from the front page when it's set to an alias

Problem/Motivation

See 📌 Front page always redirects to /home Active and 🐛 Updating page.front Active .

If you set the front page to point to an alias (only possible via manually updating configuration, or as in Drupal CMS's case, using a recipe, RouteNormalizerRequestSubscriber will redirect away from the front page to the route.

I think the event subscriber could check for '/' and return early in that case, so that there's no redirect.
