FWIW, these uBlock Origin rules solve the ploblem:

    ||accounts.google.com/gsi/iframe
    ##iframe[src^="http://accounts.google.com/gsi/iframe"]
    ##iframe[src^="https://accounts.google.com/gsi/iframe"]
    ##iframe[src^="//accounts.google.com/gsi/iframe"]
    ###credential_picker_container

source: https://stackoverflow.com/a/78429389. Last rule is from me since popup was invisible but still blocked the content underneath.

Good information, but you can already turn this off via the (quite hidden, I admit) setting that is mentioned in the article. That's a better way to turn this off completely, rather than patch it via a visual rule.

		Brave browser does not have an option to turn it off but uBlock Origin custom filter works. In the Brave community the only solution offered was an adblock filter: brave://adblock (custom filter) \|\|accounts.google.com/gsi/client$script,third-party https://community.brave.com/t/annoying-login-with-google-pop...

		The article mentions a setting in Chrome only. Someone using uBlock Origin is not using Chrome.

		Either way it's something you'd need to go out of your way to configure any time you interact with a new web browser. And both ways can be disabled randomly (Chrome settings changes during browser updates, or uBlock extension being deprecated).

The irony of getting that popup on Stack Overflow when I clicked that link
