h1 font-size in section
The stock html.css renders h1 tags inside a section with equal size as h2 both in and outside a section.
If h1 font-size is different inside a section than also a h2 font-size is expected to have different, smaller size.

That is odd: https://jsfiddle.net/1v2L9Lkm/
This is the internal rules file that scales down h1 depending on how many of article, aside, nav, or section it is nested in. As you point out, that does not apply to other heading types.

I don't know if this will be changed (maybe there's a standard??), but you could file a bug: https://bugzilla.mozilla.org/
Until then, you would need to override the built-in rule with your own CSS.
