…ecorators (LANGERGabrielle)This PR was merged into the 5.4 branch.Discussion----------[DependencyInjection] Fix AsEventListener not working on decorators| Q             | A| ------------- | ---| Branch?       | 5.4| Bug fix?      | yes| New feature?  | no| Deprecations? | no| Tickets       || License       | MIT| Doc PR        |When using the `AsEventListener` on a decorator, it is ignored instead of registering the decorator as an event listener. This is because autoconfigured tags are not applied to decorators since#30417.`EventSubscriberInterface` works as expected since#38999, when the `kernel.event_subscriber'` tag was added to a list of "behavior describing tags" which can be autoconfigured onto decorators.This PR adds `kernel.event_listener` to this default list of tags, making `AsEventListener` work as expected on decorators.Commits-------5fbb217 Added `kernel.event_listener` to the default list of behavior describing tags, fixing AsEventListener attribute not working on decorators.
