[kube-prometheus-stack] Gafana Home Dashboards resets

[PaintedShepherd]

Describe the bug a clear and concise description of what the bug is.

I have deployed a new dashboard and i am using it as the home dashboard. When i patch my infrastructure and the grafana pod ist moved to a different node the home dashboard is being reset to the default grafana home dashboard. Is it possible, that the grafana dashboard sidecar is running after grafana sets up and searches for the home dashboard.

How to reproduce it?

deploy kube-prometheus-stack
add configmap with new dashboard
wait until dashboard is read and availible in grafana
