Expected behaviour

Clicking on a test in the test explorer should navigate to the correct test in the correct test file.

Actual behaviour

Clicking on a test in the test explorer navigates to the correct test file but the cursor ends up in a random place in the file.

Steps to reproduce:

1. Have the following folder structure:

root/
   .vscode/settings.json
   hello.py
   tests/
         test_file.py

with test_file.py containing

"""Example test"""


def test_file_one():
    print("hello")
    assert True


def test_file_two():
    print("world")
    assert True

and hello.py containing print("hello world").

2. Activate the python extension by opening hello.py
3. Discover tests using pytest
4. Expand the test folder structure and click on test_file_one and then test_file_two
5. Observe that not only is the cursor not located at the def test_file_one line, but it also doesn't move when clicking on a different test.
