Comment (by asafm7):

 Hi @ryokuhi ,

 Thank you so much for the update.

 Here are my thoughts:
 - I'm not sure about it being an edge case - it happens every time there
 is a subheading in a post, which is quite common I guess, and the blog
 page is set to display full posts, which is one of 2 available settings.

 - I'm not sure about it being in the plugin territory. Such basic HTML
 feels core-y to me...

 - I understand it is not just Twenty Nineteen related - maybe it should
 move to another forum?

 - There are 3 possible issues here:
   1. Confusing design - subheadings look like posts titles
   2. Accessibility
   3. SEO (which I didn't mention before). I'm not an expert, but archive
 pages are getting indexed by search engines. It makes sense that the
 flattened heading hierarchy makes it more difficult for search engines to
 understand what's on the page. In general, I believe that headings are
 crucial and basic SEO factors.

 - About the issue with h6 - I thought about it too. But I believe this is
 a ''true'' edge case. I believe not many blog posts use h6, and then you
 add the conditions needed to reproduce the issue - which makes it even
 less likely for h6 to be an issue. Anyway, an h6 heading can't be mistaken
 as a post title (it has a different size and design than a post title).
 The biggest issue is h1 and h2 being merged together and being mistaken
 for each other (both by humans and robots). It makes sense that content-
 wise as well h6 are less significant - and so having less effect on SEO.
 So, the solution for h6 doesn't need to be perfect. It can stay, for
 example, as h6.

 These are my thoughts anyway.

 Thanks again.
