If getComputedStyle were to report 6px instead of 18px for visited links, I could have this page generate a link to pornhub.com, then test its font size, in order to reveal your browsing history. I could then serve you targeted ads, sell your data, blackmail you, et cetera. This security hole has been plugged by not allowing a:visited to set the font-size.
