Test Explorer is not displaying the tests with :: correctly

[StellaHuang95]

Steps to Reproduce

1. Install the python workload.
2. Create a python project.
3. Set up the python environment, install pytest to the environment.
4. Go to project properties and set the test framework to pytest
5. Add a new python file test_1.py and add the code below to it.

def ischildnode(baseid, nodeid):
    return nodeid.startswith(baseid)

import pytest
@pytest.mark.parametrize(
    "baseid, nodeid, expected",
    [
        ("foo/bar::TestBaz", "foo/bar::TestBop", True),
    ],
)
def test_ischildnode(baseid, nodeid, expected):
    result = ischildnode(baseid, nodeid)
    assert result == expected

6. Open Test Explorer

Current behavior

Expected behavior
-PythonApplication8
-test_1.py
-test_ischildnode[foo/bar::TestBaz-foo/bar::TestBop-True]

Response from the TE team:
The FullyQualifiedName needs to be in a C#-similar format in order to work in this case. Give that there are embedded '.'s in some of the segments, that probably won't work. I would definitely suggest adding the hierarchy property to all of the test cases, as in the document I linked. It can be completely configurable and won't rely on FQN parsing.
