Doesn't work with webpack, ts-loader, babel with tsconfig.json > target: "es5" configuration.

// webpack.confg.js snippet:
rules: [
  {
    test: /\.tsx?$/,
    exclude: /node_modules/,
    use: [
      {
        loader: "babel-loader",
        options: {
          presets: ["@babel/preset-react"],
          plugins: [
            "transform-react-pug",
            // "@babel/transform-react-jsx"
          ]
        }
      },
      {
        loader: 'ts-loader'
      }
    ]
  }
]

With target: "es6" it works whether "@babel/transform-react-jsx" plugin is used or not.

// tsconfig.json
{
  "compilerOptions": {
    "jsx": "preserve", // works whether `preserve` or `react`
    "target": "es5", // es5 doesn't work
    "strict": true,
    "module": "es2015",
    "moduleResolution": "node",
    "esModuleInterop": true,
    "allowSyntheticDefaultImports": true,
    "sourceMap": true,
    "allowJs": true,
    "baseUrl": ".",
    "paths": {
      "~/*": ["./*"]
    },
  },
  "exclude": ["./node_modules"]
}

Is this an issue with babel or this plugin?

Document this maybe?

If there is a workaround, I would love to know. Spent some time trying to fix this one character issue of changing 5 to 6...
