IntelliPrompt type hinting

I'm not sure if I am doing something wrong, or doing something unsupported. I am using 2016.1.0633. Consider the following example:

# employee.py
def create_employee(name, id):
    return Employee(name, id)

class Employee(object):
    def __init__(self, name, id):
        self._name = name
        self._id = id
        
    def get_name(self):
        return self._name
    
    def get_id(seld):
        return self._id

# manager.py
import employee

emp = employee.create_employee("Alice", 1)
print(emp.get_name())  # IntelliPrompt does NOT show employee methods
 
assert isinstance(emp, employee.Employee)
print(emp.get_name())  # IntelliPrompt does NOT show employee methods
 
emp2 = employee.Employee("Bob", 2)
print(emp2.get_name())  # IntelliPrompt does show employee methods

 I am not sure if I can, and how to, get intelliprompt to work in either of the first two scenaros. Any help would be much appreciated. Thank you!
