Problem with html tags when converting to GFM-markdown

[johnd0e]

For some reason GFM requires empty line after block-level HTML-tags, otherwise Markdown in that line is not parsed.

Here is sample of correct code:

- list item
  <details>

  - subitem
  </details>

  item _continue_ **with** formatting
- next list item

However, when I convert this source to gfm with pandoc, I get empty line not after </details>, but before it.
pandoc --to=gfm -o pandoc-output.gfm.md pandoc-input.md

- list item
  <details>

  - subitem

  </details>
  item *continue* **with** formatting
- next list item

As you can see, it is rendered incorrectly:

• list item

  • subitem
  item *continue* **with** formatting

• next list item

Pandoc version?
pandoc.exe 3.1.13
