Skipping in a teardown part of a yield fixture is not counted properly

I would like to delay skipping tests to the end of the test execution. To do so, I yield from a fixture and call pytest.skip afterwards. This is part of a more complex fixture, but boils down to a minimal example of:

@pytest.fixture()
def post_exec():
    params = {'skip': False}
    yield params
    if params['skip']:
        pytest.skip('This is skipped')

def test_skip(post_exec):
    post_exec['skip'] = True
    # do further stuff

Expected result: The test is skipped.

Actual result: The test appears twice in the statistics

pytest tests/test_x.py::test_skip --v

[...]

tests/test_x.py::test_skip PASSED                                                                  [100%]
tests/test_x.py::test_skip SKIPPED (This is skipped)                                               [100%]

================================================ short test summary info =================================================
SKIPPED [1] tests/text_x.py:207: This is skipped
============================================== 1 passed, 1 skipped in 0.02s ==============================================

Tested with pytest 6.4.2.

Reproduce the report with the minimal yield-fixture example and pytest command shown in the issue. Trace fixture teardown and result reporting; done means the test is counted once as skipped, with no passed result.
