On iPhone Safari, the homepage doesn’t maintain its position when the user navigates back using the back button when using Fakebook theme. On pressing back, the page scrolls to a random position in the timeline making it unusable. I understand Safari is not meant to be used in the first place but unfortunately Home Screen websites are opened using Safari’s rendering engine. I wasn’t able to reproduce this issue for the standard theme used here on meta. And this only happens on Safari not chrome.
It is important because it impacts users using the Home Screen button to access the website.
