**What is the current behavior?**

Using a combination of `globalObject: 'this'` and `runtimeChunk: 'single'` in `webpack.config.js` causes the following error when including the generated code in a browser:
```
TypeError: undefined is not an object (evaluating 'this["webpackChunkMyLibrary"]')
```

This issue started on Webpack v5.47.0. I believe it was caused likely caused by this commit:
https://github.com/webpack/webpack/commit/0bd1e789d48f9b3e3ca38d6c48db7c7be5380bcd#diff-820a04017e95cec05fd58ca44cd7f6c9cfa5b698a144471d5a0f523932486c56R619

**If the current behavior is a bug, please provide the steps to reproduce.**

See https://github.com/jluxenberg/webpack-use-strict-bug-report for full reproduction instructions.

My `webpack.config.js`:
```
const path = require('path');

module.exports = {
  entry: './src/index.js',
  output: {
    filename: '[name].js',
    path: path.resolve(__dirname, 'dist'),
    library: 'MyLibrary',
    libraryTarget: 'umd',
    globalObject: 'this',
  },
  optimization: {
    minimize: false,
    runtimeChunk: 'single',
  },
};
```

**What is the expected behavior?**

I see the text "hello world" printed to the console when including the generated `runtime.js` and `main.js` files.

**Other relevant information:**
webpack version:  bug occurs starting with v5.47.0. I tested with latest (v5.70.0) as well.
