Unable to infer through a class constructor even with type hints

Steps to reproduce

import astroid

func_node = astroid.extract_node("""
class Test:
    def test():
        return
class TestParent:
    def __init__(self, test: Test):
        self._test = Test()  # type: Test

    def test_class(self):
        self._test.test() #@

test_parent = TestParent(Test())
""")

for inferred in func_node.func.infer():
    if inferred is astroid.Uninferable:
        assert()


func_node = astroid.extract_node("""
class Test:
    def test():
        return
class TestParent:
    def __init__(self, test: Test):
        self._test = test  # type: Test

    def test_class(self):
        self._test.test() #@

test_parent = TestParent(Test())
""")

for inferred in func_node.func.infer():
    if inferred is astroid.Uninferable:
        assert()

Current behavior

astroid cannot infer when the object is passed into the class constructor. Only when it is created in the constructor,

Expected behavior

astroid is able to infer through the constructor.

I may just be doing something wrong, but I've been beating my head against this wall for a while now.

python -c "from astroid import __pkginfo__; print(__pkginfo__.version)" output

2.3.3

Start by running the two astroid.extract_node reproductions and tracing the func_node.func.infer() calls, comparing the constructor-created and argument-passed cases. Done means the inference loop no longer encounters astroid.Uninferable when the typed Test object is passed through TestParent’s constructor.
