            Description

            v4.7.0 introduced compilation, caching, and tagged-services for "Civi\Core\Container".

            Steps to reproduce:

            1. Observe: In Civi/Core/Container.php, "civi_token_compat" is tagged with "kernel.event_subscriber".
            2. Set "define('CIVICRM_CONTAINER_CACHE', 'never');"
            3. Find any piece of code that relies on the service "dispatcher". Set a breakpoint.
            4. Execute the code. Inspect the list of event listeners.
            5. The dispatcher should include "civi_token_compat" (Civi\Token\TokenCompatSubscriber)... but it's missing.

            The tag "kernel.event_subscriber" is scanned during compilation. However, if you disable caching, then it skips compilation, and any listeners like "civi_token_compat" (and others) are not properly detected.

            This affects some testing scenarios which rely on CIVICRM_CONTAINER_CACHE==never.

            This is an offshoot of CRM-19690.
