1. I tested with many different sites and configurations in order to narrow down the issue. The screenshots in the article are just a small sample of my tests, for illustration.
2. I'm not logged into Chrome or any Google services. I've gone through chrome://settings and disabled everything Google-related. Nonetheless, although I'm not using those Chrome features, this issue obviously could be related to the existence of those features in Chrome.
3. My goal in publishing the article was to get the issue fixed ASAP. I'm a browser extension developer, so I'm constantly testing with different browsers, including Chrome, Firefox, and Safari. It wasn't my intention to start a browser war.
4. I believe that Chrome is entirely open source, so I hope that someone familiar with the code base will take a look at this issue. The sheer size and complexity makes it a bit daunting for an outsider, but since Chromium has been adopted by other browsers such as Brave and Edge, there are outside developers already working on it.
