Thanks! Also notable, I can reproduce this on https://m.facebook.com as well (where I am logged in). If I load that page, I don't initially see the 1px stripe at the top, but if I scroll upwards, the 1px white stripe scrolls into view. I also can reproduce it one these no-login-required Facebook pages, on my Pixel 4a: https://about.facebook.com/ https://facebook.com/business/help ...though on these ones, I have to scroll downwards first, and then scroll up.
