High CPU usage because of service worker (sw.js)
Since the last update, almost each time I close a tab, Edge starts to take a lot of CPU.
In the browser task manager, I see that it's the service worker that cause this : it's written either "service worker " or I can see the url of the page I just close appended with a "sw.js"
This also happens when I open/close a new tab or even an extension (rss, password manager...)
I have disabled the setting : Allow recently closed sites to finish sending and receiving data (recommended) but this didn't change anything.
Version 83.0.467.0 (Official build) dev (64-bit)

Thanks
