Istio 1.11.2 and K8s versions

The compatibility matrix in the documentation conflicts with the release notes regarding supporting K8s versions. The matrix lists K8s 1.18 as “Tested, but not supported”. Yet the 1.11 release notes state that “Kubernetes versions 1.18.0 to 1.22.x” are fully supported.

Can someone clarify if K8s 1.18 is supported by Istio 1.11.2?
