No substitution in --gherkin-terminal-reporter output for scenario outline in pytest parametrizing way

In issue 222 and 235, I saw the same issue was addressed if the scrnario outline is in traditional Gherkin way, i.e. via Examples in feature files. But if the parametrization is done via pytest way, see doc, and the output still does not substitute the in the output. like this:

pytest --disable-pytest-warnings --gherkin-terminal-reporter -k test_default_merge -vv

(more output truncated)

Reproduce the issue with the shown pytest command and pytest parametrization pattern from the linked documentation. Trace the --gherkin-terminal-reporter output path and compare scenario-outline rendering for pytest parameters with the reported output; done means the parameter values replace the angle-bracket placeholders.
