First run OK, second run fails, from third one on is fine: Chrome/ium only

[WebReflection]

I've noticed something I am not sure is caused by current logic of this helper (btw, thanks for it) but when I have clear cache and I use this service worker everything is fine the first time, then if I reload nothing happens, the amount of requests are way fewer than initial load + reload after activation, and then again if I reload the page another time, from that 3rd time on, everything works as expected again and the amount of requests is always the same.

Have you noticed this issue too on Chrome/ium based browsers? It won't be reproducible on Firefox, as example, so I am wondering if there's something deeper going on that's worth filing at the Chromium project instead, thank you.
