Complementary landmarks and/or asides are top level

Ensures the complementary landmark or aside is at top level

Complementary content is ancillary content to the main theme of a document or page. Screen reader users have the option to skip over complementary content when it appears at the top level of the accessibility API. Embedding an <aside> element in another landmark may disable screen reader functionality allowing users to navigate through complementary content.
