A reproduction of Chromium issue 395536907

Steps to reproduce

Have Chrome version 133.0.6943.53/54 installed
Open clean browser profile
Open extension management page (chrome://extensions/)
Enable developer mode
Load unpacked extension (this repository)
Open the development console for the Service Worker
Open the main UI by clicking the extension icon
DON'T open the dev console for the main UI (as having it open at the time of the bug will prevent the bug from happening)
Wait for 30 to 60 seconds.
The Service Worker developer console will print an error once it loses event attachment.
