Reason is displayed only once when tests are skipped dynamically with item.add_marker(pytest.mark.skip(reason))

After adding skip markers dynamically to tests based on a certain condition, as explained in the pytest documentation here, xdist displays the reason only once on the test result summary if running with multiple workers instead of displaying for each skipped test.

Suppose you have a code like below in conftest.py:

def pytest_collection_modifyitems(items, config):
    for item in items:
        if condition_to_skip_is_met():
            reason = f"Cannot run {item.nodeid} because you didn't configure everything."
            item.add_marker(pytest.mark.skip(reason))

The results are like below:

Start by reproducing the example from conftest.py, using pytest_collection_modifyitems with dynamically added skip markers and xdist with -n 3. Trace the skipped-test reporting and summary handling; done means every dynamically skipped test displays its own reason in the output.
