ResourceResolverFactoryActivator.bindResourceDecorator never called

If I register a custom ResourceDecorator after the Sling Context has been initialized it will not trigger ResourceResolverFactoryActivator.bindResourceDecorator(...) (https://github.com/apache/sling-org-apache-sling-resourceresolver/blob/master/src/main/java/org/apache/sling/resourceresolver/impl/ResourceResolverFactoryActivator.java#L608) and therefore my ResourceDecorator will never be called.

This happens in https://github.com/Adobe-Consulting-Services/acs-aem-commons/blob/e2740ca63aac981f40763917a5ec879aa2a75156/bundle/src/test/java/com/adobe/acs/commons/remoteassets/impl/RemoteAssetDecoratorTest.java#L110
