We had built this site with a transparent header that has a fixed position with the fixed header style set to scroll back. The goal was to ensure the header/navigation is visible on page load + hides as your scroll down the page + shows up as you scroll back up. All of this functionality still works however until today when you scrolled back up the site showed a background for the header until you reached to the absolute top of the page, at that point it faded the background to transparent as intended. Today this behaviour changed (without any edits on our end) in that the header background is transparent always including scrolling back. This makes the header/nav hard to see until you reach the very top of the page.
To be clear the original functionality was achieved without any custom css, it was done using the same settings that are still on.
