[Patrick Brosset <:pbro>]

This is a new test, and it looks like it's intermittent on linux.
Here's a screenshot of the failure: https://taskcluster-artifacts.net/Q5yQG1otTmS4GDNUp3ayWg/0/public/test_info//mozilla-test-fail-screenshot_p5pQql.png
The test loads a page, then loads another one in the same tab, and then expects a link to the previous page to appear as :visited.
The test fails because the :visited CSS rule does not appear in the inspector, but the screenshot shows that the link does not appear visited in the page either.
Could there be a timing issue here? I have seen in the past that Firefox seems to update the style of visited links only after some kind of delay once you load a page. So maybe this test needs to wait for an event of sorts here.
