If you're on the assistant and you're hovering over one of the (1) style reference links. it shows a url preview of the the reference. But unless you know that you have to click on the circle to keep the url preview there, it'll just disappear. I think it might be better if you move your mouse up when it's on the circle and the url preview is showing; to keep the url preview showing until the mouse moves off of it
I get why it's happening tbf, cause the space between the circle and the url preview is just the thread itself and so it's no longer mousing over. So I guess this gap needs to be spanned or something
