Currently in Firefox, header and footer are exposed as banner/contentinfo landmarks unless contained with section or article elements, we think this is too broad and these roles should only exposed if not a child of any sectioning content or main elements

the acc API mappings for the elements reflect this stricter definition:

API mapping for header and footer

> these roles should only exposed if not a child of any sectioning content or main elements

Just stressing that it's descendant, not child. For instance:

    <article><header>Not a banner landmark</header></article>
    <article><div><div><header>Still not a banner landmark</header></div></div></article>
Added the elements in the order "sectioning elements", "sectioning roots", then main. That's why they're not in strict alphabetical order.

yeah thanks, and sorry for my unclear use of the terminology.
Am I right that we want to implement this wording of the spec  "foot (nearest ancestor sectioning content or sectioning root element is body)". Could you please give me couple examples for that rule?
oh shoot, two years old review request! Marco, could you please answer comment #4?
Flags: needinfo?(mzehe)
<body><header>this is banner</header></body>
<body><div><header>This is still banner</header></div></body>
<body><article><header>This is not banner</header></article></body>

I would keep the comment closer the spec wording, something like:

Header/footer elements having a body as a sectioning root, i.e. not contained by blockquote, details, dialog, fieldset, figure or td elements, and not contained by main element or a sectioning content, such as article, aside, nav and section elements.

It turns out that this has been fixed for Firefox 57 in bug 1316285, and none of us remembered this two year old bug. Will dupe this to that other one. :)

it seems bugzilla has a lot of out-dated surprises :)
