Pytest assert rewriter doesn't see conftest plugins

[Tusenka]

I try to run pytest rewriting for custom plugins. However it doesn't load a conftest plugin at the rewrting stage
Example:
https://github.com/Tusenka/pytest/tree/disable_assertion_rewriting_external_modules_draft/testing/example_scripts/rewrite

Result:
It sees only:
['anyio', '_hypothesis_ftz_detector', '_hypothesis_globals', '_hypothesis_pytestplugin', 'hypothesis', 'pytest_twisted', 'typeguard']

pytest/src/_pytest/config/__init__.py

Line 1293 in 9e9633d

def _mark_plugins_for_rewrite(

Does it expected behavior? Or am I doing something wrong?

Yes, of course, with pleasure
