Debugging doesn't work in Visual Studio Code after upgrade to angular v17 with browser-esbuild builder

Command

build

Is this a regression?

[X] Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

16.0.1

Description

We have a task to upgrade our existing angular application from angular 16 to 17.

We followed https://update.angular.io/?l=3&v=16.0-17.0

ng update @angular/core@17 @angular/cli@17

Our angular.json looks like this:

    }
  }
}

From visual studio code, we navigate to Run and Debug section and attach to chrome. Launch.json file content

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Attach to Chrome",
      "port": 9222,
      "request": "attach",
      "type": "chrome",
      "webRoot": "${workspaceFolder}"
    }
}

Because we have set outputPath, the build application is copied here:

Debugging works from http://localhost:4200, if we ran ng serve command, but we are serving our application from URL:

https://example.com/dashboard/spa/user-management (example.com points to localhost, defined in host file of Windows)

We are using next command for build (defined in package.json):

ng build --watch --base-href /dashboard/spa/ --output-hashing all

Debugging doesn't work

Minimal Reproduction

set outputPath in angular.json and host application not from localhost:4200
