Description

The landmark-complementary-is-top-level doc page includes this failing example:

The following example FAILS the Complementary landmarks are at the top level rule:

<main>
  <p>Some text</p>
  <aside><p>An aside</p></aside>
</main>

However, that example doesn't actually fail the rule - we started passing it when #2651 was fixed. We should replace the example with something that actually fails the rule.
