No error trace on webpack, wrong line numbers make errors unsolvable

So I've set up a Vue project with Webpack, then I installed the proper loaders and moved to TypeScript inside my SFCs. It's all running good, except that the TS errors caught during build time are shown accordingly to compiled files, thus making debugging difficult.

My Webpack config looks like this:

// ...
module.exports = {
  // ...
  module: {
    rules: [
      {
        test: /\.vue$/,
        use: 'vue-loader',
      },
      {
        test: /\.tsx?$/,
        loader: 'ts-loader',
        options: {
          appendTsSuffixTo: [/\.vue$/]
        }
      },
      {
        test: /\.css$/,
        use: [
          'vue-style-loader',
          'css-loader',
          'postcss-loader'
        ]
      },
      {
        test: /\.png$/,
        use: 'file-loader'
      }
    ]
  }
}

So, the .vue files are converted by the ts-loader during build time, and I end up getting errors like this in my Webpack output:

Searching around I've came across several answers regarding source maps, but as far as I'm aware this serves devtools debugging only. How can I get the errors to match original files in order to solve them?

Reproduce the reported Vue, Webpack, and ts-loader setup from the issue, then inspect how ts-loader reports TypeScript diagnostics for transformed .vue files. No repository files or tests are named; done means build errors point to the original .vue source and line numbers rather than the generated .vue.ts file.
