Comment:

 Here's the relevant part of the spec:

 > A hierarchically correct main element is one whose ancestor elements are
 limited to html, body, div, form without an accessible name, and
 autonomous custom elements.

 [https://html.spec.whatwg.org/multipage/grouping-content.html
 #hierarchically-correct-main-element source: HTML Living Standard]

 The applicable part is that `main` has a special requirement about all its
 parent elements, and `section` is not allowed. So yes, the fix is to
 revert https://github.com/WordPress/twentynineteen/pull/190, and replace
 those `section`s with `div`s.  I don't see any styles relying on the
 element `section`, just replacing it will work– and
 [attachment:47066.diff] does that :)
