landmark-no-duplicate-banner / landmark-unique flagged in some instances but not others #450
Description
Hello,
I have observed that the following errors get flagged when there is an aside with a header that is a child of a section that also has a header:
landmark-no-duplicate-banner Via: aXe
- Document has more than one banner landmark
- Ensure the document has at most one banner landmark
- Document should not have more than one banner landmark
landmark-unique Via: aXe
- The landmark must have a unique aria-label, aria-labelledby, or title to make landmarks distinguishable
- Ensure landmarks are unique
- Landmarks should have a unique role or role/label/title (i.e. accessible name) combination
Document has more than one banner landmark
Ensure the document has at most one banner landmark
Document should not have more than one banner landmark
Here is the HTML for the document in question. The errors are flagged for the header of aside.
