Pycharm autocomplete does not work for TypeVar with bounds

When I use TypeVar with bounds in Pycharm, there are no hints related to the upper bound of the Typevar. Example:

from typing import TypeVar

class TestClass:

    def test_class_method(self):
        print("test")

T = TypeVar('T', bound=TestClass)

def test_method(test_class: T):
    test_class.test_class_method()

test_method(TestClass())

Here, I would expect the test_class method to be listed in autocomplete when I hit ctrl + space on test_class. But there is nothing. When I highlight the test_class, there is a tooltip saying correctly: Inferred type: TypeVar('T', TestClass). Is there a mistake on my side, or is it a autocomplete issue?
