nbconvert --to html skips Markdown within HTML tags

nbconvert to html skips Markdown within HTML tags

e.g.

<blockquote>
This is a sentence containing some _italic_ and **bold**  text.
   * bullet point
   * bullet point

Here's a new paragraph.
</blockquote>

nbconvert --to html will bypass the conens of that blockquote section.

(Note that if you don't put in the </blockquote>, Markdown still renders as a blockquote (to the end of th cell) AND nbconvert --to html converts properly. Apparently, nbconvert is triggered by the closing tag, not the opening tag.

This would be convenient, especially with the bootstrap-like colored boxes in JupyterLab, that show up nicely inside the notebooks:

I realize that it could be rewritten to use HTML tags, but I prefer to have it in markdown to be able to export to PDF when needed (even if the box is not included), and since I have scripts that parse the markdown headers.

Yes, it would be great if nbconvert (and by extension nbviewer) could parse those contents of HTML tags!

I prefer to have it in markdown to be able to export to PDF when needed (even if the box is not included)

When using my Sphinx extension nbsphinx the boxes will also be included in PDF output, see e.g. https://nbsphinx.readthedocs.io/_/downloads/en/0.7.1/pdf/#subsection.3.8

This could possibly also be added to nbconvert's PDF output?
