Why I can't debug Service Workers with chrome?

I almost got mad for a few weeks trying to check how a web page was updating itself. No network traffic, nothing found with Fiddler, service workers were not used, no background sync intercepted..

On the left you see the stock price updating in real time, on the bottom no network traffic was intercepted, and on the right neither any background service
