This keeps failing on the accessibility section, and looking at
the screenshots I realized why. When you press 'down', GNOME
doesn't just 'snap' to the new view, it does a smooth downward
scroll. We're often matching *while it's scrolling*, so the
needle match is right at the bottom of the screen. But then the
animation continues, so when we get to the click action (even
though we use click_lastmatch it's not *instant* in openQA),
the thing we're trying to click (the "Accessibility" section
title) is a bit further up the screen, and the click 'misses'.
So, we need to wait out the scroll then re-assert and click.
This unfortunately will make the test take about 30 seconds
longer, but I don't see another way to do it. We could maybe
shave the wait_still_screen to one second...
