Are you kidding? Closing a connection upon receipt of the ACKresponse to the SYN you sent looks like normal HTTPS web browsing? On what planet? Normal web browsing, whether HTTP or HTTPS, involves data transmission occurring in both directions between receipt of that ACK and the closing of the connection by the web browser.
Opening a web page with lots of images results in lots of connections to web servers. If I hit the stop button before the images are loaded, my browser will close those connections without receiving any data. Web pages do not normally contain lots of HTTP links to sites that aren't running web servers, so a lot of refused connections does not look like anything that can happen in normal web browsing. Port scanning results in lots of connections closed upon opening and lots of connections refused; the distinctor is the lots of connections refused.
