This scrolls these tests in response to the TestRendered event rather
than the load event so that the scroll happens after Ahem webfont loads
have completed.

It's not completely clear to me why the font load changes layout, but
despite that this seems like the most likely cause for the tests flaky
failures due to slightly incorrect scroll position.
