Symfony version(s) affected: 4.4.13 (introduced with 4.4.8)

Description
We have defined in the framework.yaml an own cache pool. We are also decorating that cache.pool. After this the
\Symfony\Component\Cache\DependencyInjection\CacheCollectorPass is throwing an ServiceNotFoundException. It seems so that the definition name changes while decorating.

How to reproduce

• Create a new cache pool in framework.yaml
• Decorate it
• Container cannot be created anymore due missing definition

Possible Solution
Check in addToCollector is it an alias or an actual definition
