Issue: I'm not sure if tabindex="0" is the problem here, but somehow when popup windows appear (like "Which types of privilege do you enjoy"), the heading get the focus, and my screen reader tells me that it's an interactive component while it's not. Solution: Make sure you're not using any aria or tabindex that makes the browser or a screen reader think that the heading is an interactive component.
