At least in Safari 11.0.2 (macOS 10.12.6) link tracking does not work. The selector #link2:active::after appears to always exist in Safari 11.0.2 ("active" is being disregarded). I clicked on none of those links, I have never visited google.de, but results.php page told me all 3 links had been clicked. EDIT: formatting, remove word.
