Processing of Markdown inside `<summary>` tag: difference between github.com and GitHub Pages

[vadimkantorov]

If so, it appears that rendering on GitHub.com has display:inline-block for <summary> tags and looks like this:

And on GitHub Pages + Jekyll with markdown: GFM processor it turns out as

Adding

markdown: CommonMarkGhPages
commonmark:
  options: ["UNSAFE", "SMART", "FOOTNOTES"]

does not help

The code is:

<details>

<summary>

# Header

</summary>

Para*graph*

</details>

How can I render this in GitHub Pages to be identical to github.com?

@anticomputer Or should this issue be transferred to https://github.com/github/cmark-gfm/issues , if it's more relevant there?

Thanks :)
