Symfony version(s) affected: 5.2.4 (maybe also 4.4.x? see StackOverflow reference below)

Description
Setting access_decision_manager.strategy from the main /config/packages/security.yaml file while using other /config/packages/ENV/security.yaml files to fine-tune some other options results in the strategy value being overridden by the default (affirmative).

I think that this may be related to: https://stackoverflow.com/questions/61520675/symfony-access-decision-manager-strategy-is-always-affirmative

Am I doing anything wrong?

How to reproduce
Here is a reproducer: https://github.com/liarco/symfony-access-decision-strategy-config (the README contains complete instructions and output examples).

Thank you for your time.
