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 thekernel.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, makingAsEventListener
work as expected on decorators.
