            "sourceMap": true      // <--- This setting should be included by default
          }

Mention any other details that might be useful

When this setting is not included in the project, ng test --code-coverage produces incorrect coverage reporting for the Angular project. The sourceMap setting must be added to the CLI settings to get correct coverage reporting.

Please include this setting in all new projects generated by the CLI.

When using the CLI to upgrade to a new angular version, if this setting is not explicitly set in angular.json, the setting should be added.

Please update the CLI so that it sets the right config out of the box.

Thanks
