{Note: to make sure it's clear, this is the request to actually remove
("ship") the special rules, in M140.}
Contact emailsmas...@chromium.orgExplainerNone Specificationhttps://github.com/whatwg/html/pull/11102 Design docs https://github.com/whatwg/html/issues/7867#issue-1218728578 Summary The HTML spec contains a list of special rules for <h1> tags nested within <article>, <aside>, <nav>, or <section> tags: https://html.spec.whatwg.org/multipage/rendering.html#sections-and-headings These special rules are deprecated, because they cause accessibility issues. Namely, they visually reduce the font size for nested <h1>s so that they "look" like <h2>s, but nothing in the accessibility tree reflects this demotion.

Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).
