Describe the bug

Stdout created in functions not defined in the code block itself will not be rendered (but shows up in the stdout of the mkdocs run)

To Reproduce

I expect the same rendered output in all three code blocks below:

print("hello")

def hello():
    print("hello")
hello()

from somepackage import hello   # same definition of hello as before
hello()

The last block executes, and its output shows up in the mkdocs stdout, but the "result" block created by markdown-exec remains empty.

Expected behavior

All three blocks should give the same result.

System (please complete the following information):
mkdocs 1.4.3
markdown-exec 1.6.0
Platform: linux
OS: posix
Python: 3.9.16
