Bug introduced by
It seems like $container->get($id) can also be of type object; however, parameter $arrays of array_merge() does only seem to accept array, maybe add an additional type check? ( Ignorable by Annotation )

If this is a false-positive, you can also ignore this issue in your code via the ignore-type  annotation

32
                    $tags = array_merge(/** @scrutinizer ignore-type */ $container->get($id), $tags);
