New submission from Drekin:
Let's have a simple script test.py:
def f():
return x
x = 2

Now if we try to run it via runpy.run_path, we get the following:
import runpy
g = runpy.run_path(test.py)
2
g[f]() is None
True
g[x] is 2
True
g[f].__globals__[x] is None
True

#18214. This means that all values (except __builtins__) are replaced by None.
To work around this run_path() apparently returns a *copy* of the globals dict
which was created
