A popup shows telling "No defintion found"

[hlovdahl]

1. Put cursor on an instance declaration of a class in the same file.

Example:
class MyClass():
...
my_class = MyClass()

2. Press Ctrl+Alt+g

Expected behavior:
It would find the MyClass-declaration

Actual behavior:
A popup shows telling "No defintion found"

I am using ubuntu 20.04, python 3.8, atom 1.54.0, autocomplete-python-jedi 1.10.3-0
