To get straight to the point, I've put "#title-text { display: none;}" into my global stylesheet in the Admin settings. It works when I first load the page, but when I scroll the page title comes back into view. I have to refresh one to two times before it gets hidden again, then comes back as soon as I scroll.
I'm not sure why I'm seeing this behavior, and I'm seeing it across devices and after clearing cache completely. Here's a quick gif of the issue https://imgur.com/a/aBoQ4Nm.
