We've been seeing an odd case lately where the language select
screen is not foregrounded when it appears (so all text is
grey). It happens very occasionally on x86_64, but a lot on
ppc64. To work around this, let's add a needle that matches the
inactive screen, and click on the screen when it appears just
to make sure it's active.
