Descendant cells executed regardless of mo.stop

[jakub-mikians-airspace-intelligence]

Describe the bug

Hi!

In the documentation it writes that stopstops "any descendants of this cell that were previously scheduled to run will not be run" . Now I run the following simple code with stop condition, and I see the last cell (the descendant, correct?) that is still being executed.

The expected outcome is that the last cell is not executed. Or did I read the documentation incorrectly? If that is not the purpose of mo.stop, then please clarify in the doc how to stop execution of all the cells below the one that is meant to stop the program.

    mo.stop(True, mo.md("stopped execution"))
    return

    app.run()

The bottom markdown is not a dependency of the cell prior. Descendants are not "below" one another but rather reference a variable that another cell declares (like excel, descendants are not lower on the spreadsheet).

You can learn more about that here: https://docs.marimo.io/guides/reactivity.html#references-and-definitions
