Mock the chrome.csi function if not available (e.g. when running headless).
It's a deprecated (but unfortunately still existing) chrome specific API to fetch browser timings.
Internally chromium switched the implementation to use the WebPerformance API, so we can do the same to create a fully functional mock. :-)
Note: We're using the deprecated PerformanceTiming API instead of the new Navigation Timing Level 2 API on purpopse.
