### What did you do?

I'm sending OTEL from multiple K8s clusters to Elastic Serverless, and I installed the K8s OTEL Integration 2.0-preview. For K8s-OTEL onboarding, I just copy/pasted the OTEL Operator instructions from my Serverless environment's K8s Quickstart page to my K8s clusters.

### What did you see?

All of the Overview dashboard's timechart panels are breaking down values by alphabetical, and they should be breaking down values by count-desc. See screenshot. The associated panels in each of K8s Tabs (Nodes, Namespaces, Pods, etc.) all appear to be breaking down correctly by count.

### What did you expect to see?

Overview page's panels should be breaking values down by count, not alphabetica.

### Anything else?
