Prometheus stack not respecting retention

[Simone Benati]

What happened?
Prometheus isn't respecting retentionSize nor retention. And my PV keeps growing and growing

Did you expect to see some different?

Yes I expect the pv to stop growing indefinitely

How to reproduce it (as minimally and precisely as possible):

Install prometheus stack version kube-prometheus-stack-56.6.0 v0.71.2 via helm, set a retention value or retentionsize very small and see that your pvc will increase regardless

Environment

on premises, longhorn csi
