Minimal reproduction for the bug webpack/webpack#16160

1. Clone this repo
2. Install dependencies: yarn
3. Run a build: yarn build
4. Make a modification to the src/image.svg file, or run: yarn modify-image to do so automatically (appends a blank line)
5. Run a build again: yarn build

This second build will fail on a cache error To reset the cache to a clean state, run yarn clear-webpack-cache
