While working on https://issues.redhat.com/browse/ISPN-15377 it was found with the newly added test that SIFS has issues with iteration with a given request pattern.

See the test at https://github.com/infinispan/infinispan/pull/11579/files#diff-af7b5b7dbf7d9a3de4e87aabb1462e4a29fd6f250dec000015c75d46efe6f3f7R110
