sphinx-gallery scripts containing rst

[maxnoe]

The documentation of sphinx-gallery mentions jupytext and the other way around and makes some mention of converting rst to markdown when converting the scripts to notebooks.

However, there doesn't seem to be the possibility to open the text notebooks using jupytext keeping the rst syntax intact and correctly rendered.

I tried configuring:

preferred_jupytext_formats_read = "py:sphinx"
sphinx_convert_rst2md = false

but opening the scripts in the notebook interface does not render the rst content correctly and then saving them results in broken syntax, e.g. because jupytext inserts empty strings

""

as new cell markers instead of

# %%

It would be really great if jupytext could be used to edit the sphinx-gallery scripts in the notebook interface.
