No Asset replacement in ng serve

🐞 Bug report

Command (mark with an x)

• new
• build
• [ x ] serve
• test
• e2e
• generate
• add
• update
• lint
• xi18n
• run
• config
• help
• version
• doc

Is this a regression?

In the previous version works with the filereplacment option

Description

I update to Angular 10 and have an Issue with the filereplacement in the assets.

I find this bug report

https://github.com/angular/angular-cli/issues/16779

That says it’s not a bug and give an alternative, to configure different assets for each environment.

It’s works for me, but only when I run ng build, but when run ng serve, the assets not be replace

Temporary solution for me was creating assets sandwich with overriding assets both above and below with the same order:

             "assets": [
               {
                 "glob": "**/*",
                 "input": "src/second-override-assets/",
                 "output": "/assets/"
               },
               {
                 "glob": "**/*",
                 "input": "src/first-override-assets/",
                 "output": "/assets/"
               },
               "src/favicon.ico",
               "src/assets",
               {
                 "glob": "**/*",
                 "input": "src/first-override-assets/",
                 "output": "/assets/"
               },
               {
                 "glob": "**/*",
                 "input": "src/second-override-assets/",
                 "output": "/assets/"
               },
             ],
