"visited" links in a page of Google results

After doing a Google search I usually Adjust-click the ones that look
relevant, so that they open in a new window.

I seem to recall that in previous versions of Netsurf, the visited
links in the original window would change colour to show they had
already been visited. But they don't do so now in Netsurf 3.0.

If my memory is indeed right, then is this phenomenon something to do
with the CSS for the Google page, or with Netsurf's default CSS?
And if so, can I change it?

(Netsurf 3.0 on Iyonix with RiscOS 5.18, also on RiscPC with Ro 4.39
and Armini with Ro 5.19)
