Steps to reproduce

Was following this guide https://wildermuth.com/2019/04/08/Using-Vue-CLI-Inside-an-ASP-NET-Core-Project and added an additional command watch.

"scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "test:unit": "vue-cli-service test:unit",
    "watch": "vue-cli-service build --mode development --watch"
  },

// vue.config.js
module.exports = {
    outputDir: "../wwwroot/client-app/",
    filenameHashing: false,
    publicPath: "/client-app/",
    indexPath: "../../Views/Index/Client_App.cshtml"
}

I noticed that with mode development indexPath wasn't used while outputDir was still used. Is this expected behavior? When I changed the command to "watch": "vue-cli-service build --mode production --watch" the watch auto build worked fine.

What is expected?

indexPath is used while in development mode from cli.

What is actually happening?

Ignoring indexPath completely and only using defaults from outputDir.

looks like #4057 may solve this.

My version (3.9.2) still has this issue (and the underlying code that #4057 addresses). When will this be fixed?
