Bug report

What is the current behavior?
JSON produced by ProfilingPlugin is shown in Chrome with one single "Evaluate Script" line without any additional info.
Although events.json is pretty large, contains a lot of lines, timestamps, and looks like a valid JSON file.
Maybe there are some changes in Chromium itself related to this issue.

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

1. Create new project with npx create-react-app test-project.
2. Eject (cd test-project && npm run eject)
3. Add new webpack.debug.ProfilingPlugin() to plugins section at config/webpack.config.js
4. Start dev server with npm start then shutdown it (or just npm run build).
5. Drag and drop generated events.json into the Chrome DevTools Profiler.

Or just unarchive and use attached events.json

P.S. I can reproduce issue in all my projects, with different configs, and none of them uses CRA. It's just easy-to-check example with wide used and probably well tested config.

What is the expected behavior?
I exepect to see some additional info, eg timings for each used plugin, "Bottom-up" list, etc.
