myst-parser handling of example code blocks containing autosummary directives

[ESKYoung]

Hi,

I'm writing some brief documentation for users on how to use autosummary with myst-parser. To help my users, I've written a brief example in a Markdown code block, like so:

# Title

Some text.

````markdown
```{eval-rst}
.. currentmodule:: my_module

.. autosummary::
    :toctree: folder/

    hello
    world

```
````

The module my_module and its functions hello and world do not exist, as this is just an example.

However, when I build the documentation with Sphinx, it actually executes the autosummary directive, and raises warnings:

WARNING: [autosummary] failed to import 'my_module.hello': no module named my_module.hello
WARNING: [autosummary] failed to import 'my_module.world': no module named my_module.world

Is this the expected behaviour? Or am I doing something wrong?! I would've expected it to skip over the entire {eval-rst} block as it's nested inside a code block. Grateful for any assistance!
