This limitation is currently tracked at #12454 [https://github.com/cilium/cilium/issues/12454]

The policy tracing framework allows to trace the policy decision L7 policies at egress, the source identity context is lost as it is currently not carried in the packet. This means that traffic will look like it is coming from outside of the cluster to the receiving
