in PodUtils.cancelQueueItemFor(Pod pod, String reason), 

https://github.com/jenkinsci/kubernetes-plugin/blob/master/src/main/java/org/csanchez/jenkins/plugins/kubernetes/PodUtils.java#L78C24-L78C66

all items in the Queue that have a url that matches the runUrl annotation of the pod that should be cancelled, are cancelled 

BUT: in the same jenkins-build, all agents (not necessarily pods, can be VMs also) created in that build will have the same runUrl annotation => if one of those pods fail and should (legitimately)  be cancelled/deleted, all other agents (not necessarily pods) of the same build that are waiting in the queue at the time PodUtils.cancelQueueItemFor() is called are also going to be cancelled, even if those pods are not related to the failing pod
