So in recent months, an update to Chrome caused it to hide the top bar (avatar, tabs button, and hamburger) when I'm on the home screen ("Discover", "Following") and I've scrolled downwards.

So when I'm done or I reach the bottom, rather than scroll manually to the top, I tap the URL bar and enter a very specific search term. So Google should know, every time I enter this search term, it's me doing a workaround to close the tab as efficiently as possible.
