Aside should not be contained in another landmark
What is the problem?
The "landmark-complementary-is-top-level" rule ensures that complementary content, marked with the role="complementary" attribute or an <aside> element, is not nested within other landmarks like banner, contentinfo, or main.

Why is this important?
Nesting complementary content within other landmarks can create a confusing document structure for screen reader users. This can make it difficult for them to understand the page's organization and navigate efficiently.
How to solve this issue
To fix this issue, ensure that complementary content is a top-level element in the document structure. It should not be nested within other landmark regions. This will help screen reader users understand the relationship between the complementary content and the main content of the page.
